To conjugate a predicate in the past tense, a pre-final ending past tense ending is added to a predicate.
Conjugating the predicate in the past tense follows these steps
• Add ㅓ or ㅏ to the predicate stem.
• Then add ㅆ as a 받침 to the final syllable.
If the predicate is conjugated in the intimate speech level then 어 is added as the final syllable. If the predicate is conjugated in the polite speech level then 어요 is added as the final syllable.
The past tense may also be used to describe a recently completed action. For example, if an office worker is already inside the office after arriving, this office worker can say the following phrase.
When an additional 었 is added to the first past tense marker, the predicate's meaning is becomes more remote than the recent past. For example, or This can be used when recounting events which are in the distant past and no longer immediately relevant.
