Notes
something the speaker proposes doing. Put a request or a command after て
and the sentence flips back to plain sequencing: 座って待って
is "sit down and wait", not "wait because you sat down".
Related patterns
Similar
から asserts the reason as the speaker's case and licenses a command, request or invitation after it (寒いから閉めて); causal て only presents the cause and takes none of those — ×寒くて閉めて cannot be a reason.
ので names the causal link explicitly and survives in written explanation and formal apology alike; causal て leaves the link unnamed and needs the second clause to supply it, which is why て is normal before a feeling word and thin before a bare statement of fact.
Opposite
- なくてpositive-vs-negative-cause
The same causal link on opposite polarities — 間に合って安心した against 間に合わなくて焦った; なくて is the only negative shape available here, because ないで states a manner and never a cause.
Lookalikes
The identical surface splits on what follows it — a further willed action reads as sequence (会って話した), while an emotion, an evaluation or an uncontrollable result reads as cause (会えて嬉しい); it is the second clause that decides, which is why learners take causal て for plain listing.
