🤝 提 = lift + 携 = lead by the hand: two companies lift the work together = tie-up
提 means lift or raise, and 携 means lead along by the hand. Together they describe partners carrying a joint project forward side by side, which is what 提携 means in business.
提 — hand radical 扌 + 是 (phonetic)
提 is a semantic-phonetic compound. The hand radical 扌 gives the meaning, since the character originally referred to lifting or carrying something by hand. The right side 是 supplies the sound. From 'lift up' it extended to 'raise (an issue),' 'mention,' and 'bring forward.'
