Nouns with one form

Aircraft irregular as a plural noun in English since it doesn’t end in -s/-es, which is the suffix that regular plural noun forms take. This is why aircraft plural is often mistaken for aircrafts, despite it being simply aircraft (as a plural.)  

Aircraft are not the only irregular English plural noun that remain the same in both singular and plural forms. Beer, deer, moose, shrimp, all stay the same in both their singular and plural noun forms. While this sounds counterintuitive, and possibly discombobulating, in most cases, it’s pretty straightforward to tell whether what’s mentioned is plural or singular.

In the case of aircraft: it’s safe to assume that if it’s mentioned at, say, an airport, it’s probably referring to more than one aircraft. If what’s being referenced are aircraft in-flight, then chances are it’s either one or two aircraft (unless referring to a war-time setting.) For other plural nouns that stay the same (and are irregular), such as fish, salmon, shrimp, trout, and moose. Though it sounds difficult to tell whether it a noun is singular or plural if there is no evident change in the word itself, it’s actually quite intuitive.
