With too much capitalisation, have typo corrected (3-5)
I believe the answer is:
top-heavy
'with too much capitalisation' is the definition.
(as in an overcapitalised business)
'have typo corrected' is the wordplay.
'corrected' indicates an anagram.
'have'+'typo'='havetypo'
'havetypo' is an anagram of 'TOP-HEAVY'.
(Other definitions for top-heavy that I've seen before include "Unstable through being over-loaded at the higher end" , "With upper part too weighty" , "Likely to fall over" , "(Of company) having too many executives" , "Unbalanced" .)
