Dual number
Dual number is a grammatical number equal to 2. This is a feature of English grammar, albeit one that’s marginally present in English. Generally, in English, these are treated as a type of plural.
Examples include scissors, pants, trousers, etc. A "pair of,” or a “couple of" can be used as quantifiers. The parse test for dual number nouns is “can we use 'a pair of' as a quantifier"?.
English language learners may be reminded that they have two legs, so need a one trouser for each leg (and thus a pair of trousers). In other languages, the corresponding words may be singular.
The indefinite pronouns/adverbs, “both,” "either" and "neither" are dual.
