Questions & Answers about asa wa kaze ga tsuyoi desu.
が is the subject marker here. Within the topic “morning,” 風 (“wind”) is the subject that “strong” applies to.
- は would turn 風 into a new topic, shifting focus.
- を marks a direct object, but here nothing is being acted upon; you’re describing a state.
So 風が強い means “the wind is strong.”
They serve different roles:
- は picks out the topic or context (here, “the morning”).
- が marks the grammatical subject that has the property or performs the action (here, “the wind”).
In “朝は風が強い,” you’re saying “As for the morning (は), the wind (が) is strong.”
