Answer. The correct answer to the question, singular of Lice is Louse is A) Yes. The word lice is the plural form of louse. A louse is a small, wingless insect that often infests the hair or clothing of humans and animals.
Complete Answer.
The singular of lice is louse. This might sound unusual because louse does not follow the regular pluralisation pattern in English, where most nouns simply take an -s or -es ending, like pen becomes pens or brush becomes brushes. Instead, louse is an example of an irregular plural, much like mouse to mice or goose to geese.
Irregular plurals in English often have linguistic roots in Old English or Germanic origins. These older forms followed different rules for making plurals, rules that still exist in modern English, especially in frequently used nouns.
