Learner in love, albeit flat on the floor (4)

I believe the answer is:
lino
'albeit flat on the floor' is the definition.
I can't judge whether this definition defines the answer.
'learner in love' is the wordplay.
'learner' becomes 'l' (as in a learner driver with L-plates on their car).
'love' becomes 'o' (love means zero in tennis).
'l'+'in'+'o'='LINO'
Can you help me to learn more?
(Other definitions for lino that I've seen before include "put this down?" , "'Floor covering, in short (4)'" , "Tough floor covering" , "Floor covering (abbr)" .)
