Native in old garb at home meeting a lecturer (8)
I believe the answer is:
original
'native' is the definition.
(I've seen this before)
'old garb at home meeting a lecturer' is the wordplay.
'old' becomes 'o' (common abbreviation eg in OE for Old English).
'garb' becomes 'rig' (rig is a kind of garb).
'at home' becomes 'in' ('in' can be similar in meaning to 'at home').
'meeting' says to put letters next to each other.
'lecturer' becomes 'l'.
'o'+'rig'+'in'+'a'+'l'='ORIGINAL'
'in' is the link.
(Other definitions for original that I've seen before include "Not copied or imitated" , "Prototype" , "derivation" , "Not derived or copied form something else" , "In first form" .)
