Which meaning of a word expresses the relationship between a linguistic event (speaking or writing) and a nonlinguistic event (an object, idea, or feeling) ?

Semantic meaning.

Explanation:

As it is stated, the semantic or denotative meaning of a word makes reference to its properties and how they establish the way in which a word will be implemented in its language system. For example, saying "car" relates to a vehicle in which you get into, whereas saying "guitar" relates to an object used to make music.
