Autistic and Autism: What Each Word Means and Which One to Use

Dictionary: Autism (ASD) · Autism Resource Centre (ARC)

Autism, autistic, ASD: three words for one thing

The three words do different jobs in a sentence. They do not point to different conditions.

• Autism is the noun, the name of it: “your child’s autism”, “learning about autism”.
• Autistic is the adjective, the word that describes a person: “an autistic child”, “I am autistic”.
• Autism spectrum disorder (ASD) is the medical name. KKH describes autism spectrum disorder as “a developmental condition that can be identified in early childhood”. Developmental means it is about how a child’s brain develops.

KKH says the word “spectrum” is there because people with autism show different levels of autism-related behaviour. In plain words, no two autistic children look alike. Our SG Autism Dictionary entry on autism explains the spectrum, and why we call autism a difference rather than an illness.

“Disorder” is the medical label on the form. It is not a verdict on your child.

If the diagnosis is still new and the word feels heavy, our guide to coping in the first weeks after your child’s autism diagnosis is a gentle place to start. If you are still waiting for an assessment, our gentle self-check for parents covers the everyday patterns to watch for.

Two ways of saying it

There are two common ways to put it, and a third that sits between them.

The names come from what comes first in the phrase. In identity-first words, such as “autistic child”, the identity, autistic, comes first. In person-first words, such as “child with autism”, the person comes first, and autism is something they have.

A large UK survey of 3,470 people was published in 2016 in Autism, a research journal. It found that “autism” and “on the autism spectrum” were the most widely accepted terms, and every group agreed on them. In that survey, it was the phrase the groups could share.

What autistic adults say, in Singapore and elsewhere, and why

In the surveys from Singapore, the UK and the US, the same split shows up. Autistic adults lean towards “autistic”. Professionals lean towards “with autism”. Parents and caregivers land in different places in different countries.

In Singapore. A team at KKH asked 320 people here how comfortable they were with common autism words, on a scale from 1 (uncomfortable, I do not like this term) to 7 (very comfortable, this would be my preference). The group was 38 autistic adults, 86 caregivers and relatives, and 196 professionals who work in the autism field. The study was published in the journal Autism in May 2026.

Read across a row and the pattern is plain. The word autistic adults liked most is the one professionals liked least, and the other way round.

Only 38 autistic adults took part, so treat the exact scores with care. The direction matches the larger surveys abroad.

The researchers think Singapore’s relatively conservative culture, meaning a more traditional one, and its views on autism likely shaped these preferences.

Elsewhere. In a US survey published in 2023, autistic adults “overwhelmingly” preferred identity-first words, while professionals were more likely to use person-first ones. A North American study published in 2025 found that both autistic and non-autistic adults ranked identity-first words higher.

Why “autistic”. That North American study asked people to explain their choice. Of those who ranked an identity-first word highest, 66% said they liked it because it affirmed autistic identity. In other words, the word treats being autistic as part of who they are.

One participant put it this way: “Autism is part of who I am. It’s part of my identity and I want to reflect that.”

Almost half of those who ranked person-first words lowest, 49%, said those words make autism sound like a disease or a disorder.

Why “with autism”. People who prefer person-first words want to put the person before autism. The aim, in the words of the US study, is “to reduce stereotypes and discrimination and emphasize the person’s individuality”. That is a kind aim too.

Is it wrong to say a child “has autism”?

No. It is not rude, and it is close to the wording KKH and MOE use (see the table below).

There is no single right answer, even among autistic people. The UK survey concluded that no one way of describing autism is accepted and preferred by everyone in the UK’s autism community.

A Dutch survey of 1,026 autistic adults found that 68.3% preferred person-first words, as did 82.5% of the 286 parents. The North American study found some autistic adults strongly prefer person-first words too.

So the kind rule is short. Ask, then use the word the person uses.

While your child is young, the word at home is yours to choose. Once your child is old enough to have a view, their choice wins, even if it differs from yours or ours.

The words Singapore agencies use

You may meet three or four phrases in one week of appointments. Here is what each agency writes on its own page.

None of these four pages uses the word “autistic”. They put the person first, or say “on the autism spectrum”.

So when a letter says “child with ASD” and this site says “autistic child”, the two are not in disagreement. They are describing the same child in two styles.

Telling your child about their diagnosis

There is no perfect age. The National Autistic Society (NAS), a UK autism charity, says evidence suggests helping a child understand themselves early on can lead to more self-esteem and self-awareness. In plain words, the child can feel better about themselves and know themselves better.

NAS suggests starting to talk about autism soon after the diagnosis, or even before it, because autistic children may already notice that they experience things differently from other children.

Some children take the news badly at first, or find it hard to follow. NAS says to give them time, and not to pour in too much at once. It adds that many autistic adults say knowing about themselves is better than going through life without knowing.

When your child is small. NAS notes that parents of young children generally decide whether, when and how to tell other people. Keep the words short and true.

You might say something like: “Your brain works in its own way. That way has a name. It is called autism, and lots of people are autistic.” Then let your child lead with questions.

A social story, a short story written from your child’s point of view, can help.

As your child gets older. NAS says parents of older children should decide together with them, and respect what the child wants. A child may be happy for the teacher to know, but not the class. This is also the age to ask which word they like: “autistic”, “on the autism spectrum”, or “has autism”.

These are the NAS tips we would follow, in the order a parent can use them:

1. Learn a little first. Read enough about autism to answer the first few questions calmly.
2. Pick a calm moment. Choose a time when you are both relaxed, in a place your child knows and likes.
3. Give a little at a time. Use words that fit your child’s age. Books, TV shows and websites can help.
4. Answer honestly. If you do not know an answer, say so, and find it out.
5. Let your child choose who to tell. Once they are old enough, it is their news to share.
6. Keep the door open. Be ready for more talks and more questions later on.

NAS also suggests finding autistic adults and other autistic children your child can spend time with, especially autistic adults who can be good role models.

What to do next

When your child is ready, ask which word they like, and use it. Until then, pick the word that feels right at home, and do not worry when the hospital or the school uses another.
