Old model stuck, cut by old kind of sword (3-5)
I believe the answer is:
two-edged
'old kind of sword' is the definition.
The answer and definition are not the same part of speech.
'old model stuck cut by' is the wordplay.
'old' becomes 'o' (abbreviation).
'model' becomes 'T' (Ford Model T car).
'stuck' becomes 'wedged' ('wedge' can be a synonym of 'stick').
'cut by' indicates putting letters inside (some letters cut their way into a word).
't'+'wedged'='twedged'
'o' placed into 'twedged' is 'TWO-EDGED'.
Can you help me to learn more?
(Other definitions for two-edged that I've seen before include "Having pros and cons" , "Acting both ways (like sword)" , "Of a sword sharpened on both sides" .)
