Liked this,but ...draft? Or draught?

silent letter in asthma? what is draftier?

I will get a grid on here without a typo eventually - I have even written draught on my notes, but typed draft in my haste. Apologies all.

A few minor hitches, but a very good grid indeed.

Very nice grid with some good overlaps and red herrings, but...
Draft or draught?
Where is the silent letter in asthma?
When you have a group of synonyms, accept synonym(s) as an answer. Don't make me try to guess which of many other possible synonyms you have used as a common definition.

The th is silent in asthma

Oh no,I don't think so!

I’m with the Cat on this one. As someone who has taught British English to more non-native speakers than I care to remember, I concur that the current convention is for the ‘th’ to be silent in the word ‘asthma’.

Good grid. Much appreciated.

Enjoyed this one, even with the spelling error.
