A French physician tenses, every so often, when they remove scrubs (7)
I believe the answer is:
undress
'they remove scrubs' is the definition.
The definition suggests an adverb but the answer is not.
'a french physician tenses every so often' is the wordplay.
'a french' becomes 'un' ('a' in French).
'physician' becomes 'Dr' (synonyms).
'every so often' indicates alternate letters.
The alternate letters of 'tenses' are 'ess'.
'un'+'dr'+'ess'='UNDRESS'
'when' acts as a link.
Can you help me to learn more?
(Other definitions for undress that I've seen before include "Remove one's clothes" , "Sunders (anag)" , "Take one's clothes off" , "Nudity" , "Disrobe - uniform for ordinary occasions" .)
