We'll is a contraction meaning ‘we will’ or ‘we shall,’ used to express future intention or a plan. In pronunciation, it’s a weak, unstressed form where the syllable may reduce to a quick /wǝl/ or /wiːl/ depending on speech context, with the primary stress falling on the following word when the contraction stands in for a verb phrase. As a noun (rare in isolation), it’s typically pronounced the same as the contracted form, often functioning as a proper noun in specialized usages (e.g., a title).
