Try to attract students with directions of certain material (7)
I believe the answer is:
woollen
'certain material' is the definition.
'woollen' can be an answer for 'material' (woollen is a kind of material). I am not certain of the 'certain' bit.
'try to attract students with directions' is the wordplay.
'try to attract' becomes 'woo' (I've seen this before).
'students' becomes 'LL' (an abbreviation for learner driver written twice).
'with' says to put letters next to each other.
'directions' becomes 'en' (east and north).
'woo'+'ll'+'en'='WOOLLEN'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for woollen that I've seen before include "Fabric made from the hair of sheep" , "soft and warm" , "Like some yarn that's spun" , "Lone owl (anag)" , "Made from fleeces" .)
