What do team and teem mean?
Team is a noun meaning a group of people who work or play together, and a verb meaning to join with others or to match items. The Cambridge entry for team covers both. Teem is a verb meaning to be full of moving things, and the Cambridge entry for teem ties it to the fixed pattern teem with. One word counts people, the other describes abundance.
| Word | Part of speech | Core meaning | Example sentence |
|---|---|---|---|
| team | noun | A group working together | The design team meets on Mondays. |
| team | verb | Join together or match | She teamed a linen jacket with old jeans. |
| teem | verb | Be full of moving things | The rock pool teems with tiny crabs. |
The dedicated team page explores the group sense on its own, and the teem page drills the with pattern in more detail.
One limitation is worth stating plainly. Teem is rarely used without with, and it never means to gather people into a group, which is team’s job. Team, for its part, cannot describe a place overflowing with things, so the two are not interchangeable in either direction. A quick test is to try the word up: if you can team up with a colleague, the noun or verb team is right, while a street teems with people and never teams up.
How do you use team and teem in a sentence?
Team works as a noun, as a verb with up or with, and in the phrase a team of. Teem works only as a verb, and it normally needs with to name what fills the place. If you can drop with and keep the sense, you probably want team instead.
| Pattern | Example | What it signals |
|---|---|---|
| a team of + noun | A team of nurses covered the night shift. | Names a working group. |
| team up with + person | We teamed up with the local choir. | Joining forces for a shared task. |
| team + object + with + object | He teamed a grey tie with a blue shirt. | Matching two things together. |
| teem with + noun | The harbour teems with small boats in summer. | A place full of moving things. |
| be teeming with + noun | The garden is teeming with bees. | Continuous, lively abundance. |
When the idea is simply plenty rather than swarming, the commoner words are abound and full of.
