Soaked head of school, strange, given directions (6)
I believe the answer is:
sodden
'soaked' is the definition.
(synonyms)
'head of school strange given directions' is the wordplay.
'head of' says to take the initial letters.
'strange' becomes 'odd' (I've seen this before).
'given' is a charade indicator (letters next to each other).
'directions' becomes 'en' (east and north).
The first letter of 'school' is 's'.
's'+'odd'+'en'='SODDEN'
(Other definitions for sodden that I've seen before include "Drenched, really soaked" , "Made very wet" , "Waterlogged" , "Thoroughly wet, soaked" , "Drenched through, really wet" .)
