However, we can understand your question as asking for examples of phrases that convey uncertainty or lack of specificity. Here are some examples:
Phrases with indefinite pronouns:
* Somebody's car (we don't know who owns the car)
* A few days ago (we don't know the exact date)
* Something important (we don't know what's important)
* Anywhere in the world (we don't know the specific location)
Phrases with indefinite quantifiers:
* A lot of people (we don't know the exact number)
* Several times (we don't know the precise count)
* Some of the books (we don't know which specific books)
* Many years later (we don't know the exact number of years)
Phrases with other indefinite words:
* A long time ago (we don't know the exact duration)
* In some ways (we don't know which specific ways)
* For whatever reason (we don't know the reason)
* On occasion (we don't know how often)
Examples in context:
* "I saw somebody's car parked in the driveway."
* "I met a few friends for dinner last night."
* "He gave me some advice about my job."
* "We'll meet somewhere in town."
It's important to remember that indefinite phrases are often used in conjunction with other grammatical elements, like nouns, verbs, and adjectives, to create complete sentences or clauses.
