Usage notes

Alongside -ie / -y and -ette, -let is one of the three most productive diminutive affixes in modern English. It is used almost exclusively with concrete nouns and (unusually for a diminutive) never with names. When used with objects, it generally denotes diminution only in size; when used with animals, it generally denotes young animals; when used with adult persons, it is generally depreciative, connoting pettiness and conveying contempt. When used to describe parts in a suit of armor and some other contexts it denotes a piece or component of the larger whole.
