Start with the parts or the whole

  • Parts first. Five tiles compose the wing. The five tiles make up the wing.
  • Whole first. The wing comprises five tiles. The wing consists of the five tiles.
  • Whole first with of. The wing is composed of five tiles. This passive form lets you begin with the whole and keep compose.
