Partys

Partys is not a standard English plural form. The correct plural of party is parties. The form partys may appear in brand names, personal surnames, or as a misspelling in informal writing, but it is not accepted in standard English.

Origin and spelling: party comes from Old French parti, from Latin partit- meaning part. In English, most nouns ending in a consonant followed by y form a plural by changing y to -ies (party → parties). If the base ends with a vowel before y, the plural adds -s (day → days, key → keys). Therefore, partys is not used in standard English.

Uses: party has two broad senses. It can refer to a social gathering, such as a birthday party, or to a political organization, such as a political party. In legal or business contexts, a party can also mean a participant in a contract or legal proceeding (the contracting party). Phrasal uses include party games, party politics, or party lists.

Notes: in some nonstandard writing or in branding, you may encounter the spelling partys, but it is generally considered incorrect for standard prose. When referring to multiple groups or gatherings, use parties. The term party has additional specialized uses in areas such as law, entertainment, and diplomacy, and may appear in compound phrases without changing its basic plural form.
