The suffix -러 (reo) takes the sequential form, and if the preceding verb ends in ㄹ (l), the ㄹ (l) does not drop out.

E.g. 먹다 (먹으니/먹으면) (meokda (meogeuni/meogeumyeon), “to eat”) → 먹으러 (meogeureo, “in order to eat”)

팔다 (파니/팔면) (palda (pani/palmyeon), “to sell”) → 팔러 (palleo, “in order to sell”)

• -려고 (ryeogo)
• -려 (ryeo)
