The particle is pronounced with a gemination (doubling tensification), which is normally not shown in the romanisation: —ᆯ께 (*lkke) and —을께 (*eulkke).
The —ᆯ게 (lge) form is only used after verb stems ending in vowels. For verb stems ending in consonants, the form —을게 (eulge) is used instead.
The —ᆯ게 (lge) form is used in informal non-polite speech (해체), and the —ᆯ게요 (lgeyo) form is used in informal polite speech (해요체). There is no form in formal speech (해라체, 하십시오체), and —겠— (get-) is used instead.
