al·lay (ə-lā') tr.v. al·layed, al·lay·ing, al·lays
[Middle English aleien, from Old English ālecgan, to lay down : ā-, intensive pref. + lecgan, to lay; see lay1.] al·lay'er n. |
"Amid the overlapping of meanings that thus arose, there was developed a perplexing network of uses of allay and allege, that belong entirely to no one of the original vbs., but combine the senses of two or more of them." [OED]The double -l- is 17c., a mistaken Latinism.
