1. Talking about the past: This is the most likely meaning. It refers to conversations that happened in the past, or to discussions about events that have already occurred. For example:
* "We talked about our childhood memories last night."
* "The news reported on the recent earthquake."
2. Using past tense verbs: This is more of a grammatical concept. It means using verbs in their past tense form to describe actions that happened in the past. For example:
* "I walked to school this morning."
* "The sun shone brightly yesterday."
3. A specific event or gathering: This is less common, but "talk" could sometimes refer to a specific meeting or discussion, especially if it was important or historical. For example:
* "The peace talks in Geneva were a major turning point."
