Bachelors, I see, are pretty fundamental (5)
I believe the answer is:
basic
'pretty fundamental' is the definition.
'basic' can be an answer for 'fundamental' (similar in meaning). I'm not certain of the 'pretty' bit.
'bachelors i see' is the wordplay.
'bachelors' becomes 'bas' (people with Bachelor of Arts degrees).
'see' becomes 'C' (the word for the letter, according to Chambers).
'bas'+'i'+'c'='BASIC'
'are' acts as a link.
Can you help me to learn more?
(Other definitions for basic that I've seen before include "Radical" , "Key" , "Simple, unadorned" , "Popular programming language" , "Plain" .)
