verb [ɪnˈtɝpəˌleɪt]

Interpolate is a formal word used to talk about interjecting or inserting something, especially words or a musical element. A critic might interpolate a comment into a conversation, or an artist may interpolate a melody or lyric from one song into another. In mathematical contexts, the word can also mean “to estimate values of data or a function between two known values,” or “to make insertions (as of estimated values).”
