Jot about one page for a term in grammar (10)
I believe the answer is:
participle
'term in grammar' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'jot about one page for a' is the wordplay.
'jot' becomes 'ip' (I can't justify this - if you can you should give a lot more credence to this answer).
'about' means one lot of letters goes inside another.
'one page' becomes 'p'.
'for' is a charade indicator (letters next to each other).
'a' becomes 'article' ('a' is the indefinite article in English).
'p'+'article'='particle'
'ip' put into 'particle' is 'PARTICIPLE'.
Can you help me to learn more?
(Other definitions for participle that I've seen before include "Adjectival form of verb" , "An adjective maybe" , "Verb form that may be used as an adjective" , "Tracing, for example" , "part of speech" .)
