Short answer: There are no common everyday English words that form a perfect rhyme with "orange." A few obscure or proper‑name matches exist, and several near/slant rhymes are often used in poetry or jokes.

Perfect (very rare/obscure) rhymes
- sporange (a rare botanical term, variant of sporangium)
- Blorenge (a hill in Wales; proper noun)
- Gorringe (surname; proper noun)

Near/slant rhymes and commonly used forced rhymes
- door‑hinge (two‑word phrase often forced to rhyme)
- porridge
- porringer
- syringe
- forage
- storage
- foreign (depends on accent)
- orange (used in internal rhyme or repetition/joke)

Notes
- Which of these "rhymes" works depends on accent and stress; poets frequently use slant rhymes or multiword phrases to rhyme with "orange."
- If you want, I can give example couplets showing each option in use.
