Inhuman boor, perhaps, yet titular head (5)
I believe the answer is:
robot
'yet titular head' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'inhuman boor' is the wordplay.
I cannot really understand how this works, but
an anagram of 'boor' is 'robo' which is within the answer.
A single letter 't' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
'perhaps' is the link.
Can you help me to learn more?
(Other definitions for robot that I've seen before include "Mechanical man" , "Automatic worker?" , "Computer-driven entity" , "Computer-controlled machine" , "Automaton or sci-fi creature" .)
