Language & terminology

A translation guide for outdated, clinical, or harmful terms that still appear in reports, schools, social care, and health services. This is here to help people understand old paperwork and use modern respectful language today.

Important warning. This page discusses outdated and harmful terminology used about disability, neurodivergence, and mental health. Some people may find this upsetting. Terms are included only to explain and translate older records, not to normalise them.

Why this page exists

Language shapes access to support, safety, and how professionals respond. Outdated terms still appear in:

People should not be shamed for the wording they were given. Systems should be challenged when they continue using language that causes harm.

How to use this page

Historic medical terminology and why it changed

Some older records contain terms that were once used medically but are now recognised as harmful. The goal here is to explain what those terms usually meant and what we say now.

Retardation
This term appears in older medical and education records to describe what is now referred to as intellectual disability. Over time it became widely used as an insult and was recognised as stigmatising and dehumanising. Modern records should use intellectual disability or learning disability depending on UK context, with clear support needs described.
How to translate it safely
In meetings or paperwork you can say: the report uses outdated terminology. The modern meaning is intellectual disability. Please record the modern wording and describe the actual support needs.

Autism related language

Asperger syndrome
Now recorded as autism or autism spectrum. Older paperwork may still use this label.
PDD or PDD NOS
Historic umbrella terms. Now generally recorded as autism spectrum.
High functioning autism
Misleading. Often used to deny support while ignoring burnout, anxiety, sensory overload, and executive functioning needs.
Low functioning autism
Dehumanising. Replace with a description of support needs and communication profile.
Severe autism
Often reflects service capacity not the person. Describe barriers and supports instead of severity labels.
Autistic traits
Sometimes used to avoid assessment. Traits can be a reason to assess, not a reason to dismiss.
Social communication disorder
Sometimes used instead of autism when professionals are unsure. Can overlap with language disorders and autism presentations.

ADHD related language

ADD
Older term often referring to inattentive ADHD.
Hyperkinetic disorder
Older clinical label sometimes seen in NHS or older records. Now generally understood as ADHD.
Attention deficit
Misleading. ADHD is usually an attention regulation difference, not a lack of attention.
Lack of motivation
Often incorrect. Can reflect task initiation difficulty, overwhelm, demand overload, or stress.
Behavioural problems
Often describes untreated or unsupported ADHD traits like impulsivity, overwhelm, or emotional dysregulation.

Learning disability and learning difficulty

These are constantly confused in the UK. The difference matters for assessment routes, EHCP evidence, and support.

Learning disability
UK term usually meaning intellectual disability. Often lifelong and may include daily living support needs.
Intellectual disability
International term. Often equivalent to learning disability in UK services.
Learning difficulty
Usually refers to specific profiles such as dyslexia, dyspraxia, dyscalculia, and developmental language disorder. Intelligence may be typical or high.
Mild moderate severe
Better replaced with specific support needs like communication, daily living, processing, sensory, anxiety, and learning adaptations.
Slow learner
Outdated and often used when teaching is not being adapted or needs are not being assessed properly.

Speech, language, and communication

Speech delay
Non specific. Needs assessment to separate speech sound differences from language development differences.
Specific language impairment
Older label. Now generally recorded as developmental language disorder.
Non verbal
Often wrong. Many people are non speaking but still communicate and understand. Better wording includes non speaking or uses AAC.
Chooses not to speak
Often describes selective mutism, anxiety, shutdown, or overload. It is not usually a choice.

Sensory language people still misuse

Over sensitive
Often means sensory processing differences, nervous system stress, or overload risk. It is not just being dramatic.
Fussy eater
Can reflect sensory food aversion, gag reflex sensitivity, texture intolerance, anxiety, ARFID, or autistic sensory needs.
Overreacting
Often distress behaviour linked to overload, fear, pain, or unmet needs.
Attention seeking
Often better understood as connection seeking, safety seeking, or help seeking.

Trauma and mental health language

Oppositional or defiant
Can reflect fear, trauma responses, chronic overwhelm, demand distress, or anxiety driven avoidance.
Manipulative behaviour
Often mislabels survival strategies, masking, or attempts to regain safety and control.
Emotionally unstable
Broad and often unhelpful. Can hide trauma history, unmet needs, and system harm.
Non compliant
Often means cannot cope, does not understand, needs adjustments, or feels unsafe.
Behaviour problems
Often means distress behaviour, unmet needs, pain, overload, fear, or unsupported neurodivergence.

School and system language

Challenging behaviour
The behaviour challenges the environment. It often signals unmet needs.
Managed move
A school placement change. It can be genuinely supportive or it can be pressured. Always ask what the plan is and what rights apply.
Off rolling
Illegal removal of a pupil from the roll without proper process and safeguards.
SEN support
Support without an EHCP. Can be helpful but is often inconsistent without clear monitoring and evidence.
Underachieving
Often means teaching is not adapted or needs are not supported, not that the child is failing.
Not meeting expectations
Often means the expectations were not accessible in the first place.

Social care and safeguarding language

Non engaging family
Often means overwhelmed, unsupported, distrust due to past harm, or communication barriers. Ask what adjustments were offered.
Complex family
A vague label. Often hides poverty, disability, trauma, or system failure. Ask what the actual concerns are and what support is being offered.
Non attendance
Can reflect unmet needs, anxiety, unsafe environments, bullying, transport issues, or SEN not supported.
Parent unable to
Often written without reasonable adjustments, disability context, or proper support planning. Ask what support was offered and what barriers were identified.
At risk of exploitation
Often reflects unmet support needs and vulnerability in environments, not the fault of the young person.

How to challenge harmful wording without starting a fight

Final note. Language is not neutral. It shapes identity, access to support, safety, and how systems respond. Understanding and translating harmful language is a protective act.
