Dry and press one, before short visit (8)
I believe the answer is:
ironical
'dry' is the definition.
('ironical' can be a synonym of 'dry')
'press one before short visit' is the wordplay.
'press' becomes 'iron' (ironing is a kind of pressing).
'one' becomes 'i' (roman numeral).
'before' says to put letters next to each other.
'short visit' becomes 'cal' (I can't justify this - if you can you should give a lot more credence to this answer).
'iron'+'i'+'cal'='IRONICAL'
'and' acts as a link.
Can you help me to learn more?
(Other definitions for ironical that I've seen before include "Incongruous or wry" , "skittish" , "With humorously opposite meaning" , "Using mild sarcasm to imply a meaning other than the literal one" , "Involving satire" .)
