1. Someone who speaks a language other than their native language: This is the most basic interpretation. It could mean someone who learned a second language and is fluent in it, or someone who is still learning a language but can communicate in it to some degree.
2. Someone who is not a native speaker of the language being spoken: This interpretation is more specific and focuses on the context of the situation. For example, in a classroom setting, a "foreign language speaking person" would be anyone who is not a native speaker of the language being taught.
3. Someone who speaks a language that is not the dominant language of their current location: This definition considers the location where the person is speaking. Someone who speaks Spanish in the United States could be considered a "foreign language speaking person" even if they are a native Spanish speaker, because Spanish is not the dominant language in the United States.
4. Someone who uses a foreign language for specific purposes: This interpretation focuses on the reason why someone is speaking a foreign language. For example, a businessperson who speaks Japanese for work would be a "foreign language speaking person" in this context, even if they are not fluent in the language.
Ultimately, the meaning of "foreign language speaking person" depends on the context in which it is used. It's important to consider the specific situation and the intended meaning of the phrase before making assumptions.
