Tight verb form? (5)
I believe the answer is:
tense
This clue is a double definition.
'tight' is the first definition.
(associated in meaning)
'verb form?' is the second definition.
(I've seen this in another clue)
(Other definitions for tense that I've seen before include "Anxious, high-strung" , "Anxious - future, perhaps?" , "Worried" , "Future perfect? Could be" , "Anxious, nervous" .)
