I've wondered about this for a while.
I realise "handicapped" is considered to be rude.
To me (and yes, I'm sure it's been discussed before but humour me) "handicap" is just one thing that stops otherwise normal performance.
"Disabled" I find quite odd. To me, an alarm is disabled when it is switched off. Clearly people who are disabled are not switched off.
Or is it better to say "has a disability" or "has special needs". The latter gets me to because "special" sounds slightly patronising. To me.
Now, I'm sure no one who has a disability gives two hoots about what I think.
But I do wonder about these words. And as far as I know (living in Wales as I do) the welsh for disabled is "anabl" - literally, "unable" which is even worse!
How does all this come about?
