What every single American has in his eye? (5)
I believe the answer is:
gleam
'in his eye?' is the definition.
The definition and answer can be both to do with perception as well as being verbs in their base form.
Maybe they are linked in a way I don't understand?
'what every single american' is the wordplay.
'GLEAM' is hidden within the letters.
However, I am not sure how this is indicated.
'has' acts as a link.
Can you help me to learn more?
(Other definitions for gleam that I've seen before include "Faint light; (quality) shine (in eyes)" , "Brief shining" , "Ray" , "shaft" , "Brief show of soft light" .)
