1. noungroup (usu. of people)
   先生せんせいは私わたしたちを二ふたつのグループに分わけた。↗

   Our teacher separated us into two groups.

• SynonymサークルNeutralA hobby or interest club, e.g. at university; has an amateur, leisure feel. 「グループ」 covers any group, not just hobby circles.
• Synonym一群いちぐんWrittenWritten style for a flock, herd or batch of people, animals or things, as in 「一群の花」. 「グループ」 is usually people linked to each other.
• Synonym一団いちだんWrittenWritten word for a body of people or a mass of things, as in 「観光客の一団」「一団の雲」. In speech, a bunch of people is usually 「グループ」.
• Synonym群ぐんWrittenRead ぐん; mostly a suffix as in 「症候群」「魚群」, and the mathematical sense of group. For an everyday group of people, use 「グループ」.
• Synonym群れむれNeutralMainly a flock, herd or swarm of animals; also neutral in 「人の群れ」. Slightly scornful for a gang of people. Use 「グループ」 for a group with fixed members.
• Synonym集団しゅうだんNeutralA collective of many people or things, leaning written, as in 「集団行動」「集団生活」. Everyday talk about a team or small group prefers 「グループ」.
• Synonym連中れんちゅうCasualColloquial for a bunch or lot of people, often dismissive or casual, as in 「あの連中」. 「グループ」 is neutral in tone.
• Related仲間なかまNeutralPeople you do things with — companions, partners; stresses the personal bond. 「グループ」 names the group itself, not the relationship.
• Related人だかりひとだかりNeutralA crowd that gathers on the spot, e.g. onlookers; temporary, with no ties among members — unlike 「グループ」.
• Related群衆ぐんしゅうWrittenWritten word for a large crowd massed in one place, stressing sheer numbers, as in 「群衆に紛れる」. 「グループ」 is a connected bunch of people.
• Related群集ぐんしゅうWrittenBookish word for gathering or flocking together; also a verb, 「群集する」, and a biological community. Rare in daily use, unlike 「グループ」.
• RelatedモブCasualColloquial loanword for a crowd or a background character in manga, anime and games; not used in everyday talk for a team or group.
• Antonym個人こじんNeutralAn individual, one person. Opposite of 「グループ」 in the one-versus-many sense, as 「個人戦」 vs 「グループ戦」.
• Antonym単独たんどくNeutralActing alone or solo, as in 「単独行動」; the opposite of 「グループ」, which implies acting as a group.

For an everyday group or team, 「グループ」 is the default. Use 「仲間」 for companions, 「サークル」 for a hobby club, 「集団」 for a collective in written prose, and 「群衆」 for a gathered crowd.
