layer
التعريفات والمعاني
== English ==
=== Etymology 1 ===
Appears at first glance to be from Middle English leyer, leyare (“a layer of stones or bricks”), equivalent to lay + -er. In which case, ultimately identical to etymology 2 below. For the pronunciation compare prayer.
However, this word layer (referring to a thickness of a material covering a surface) has also been argued to be from a respelling of an obsolete sense of the word lair that was once used by farmers, which had to do with soil. The connecting sense between the usual meaning of lair and the specialised farming meaning was: an area where cows typically rest, the ground being fertilised by their waste. Related to lie, ledger.

==== Conjugation ====
This is a regular -er verb as far as pronunciation is concerned, but as with other verbs in -ayer (such as payer and essayer), the <y> of its stem may optionally be written as <i> when it precedes a silent <e> (compare verbs in -eyer, which never have this spelling change, and verbs in -oyer and -uyer, which always have it; verbs in -ayer belong to either group, according to the writer's preference).
