モンゴル語の存在・コピュラ動詞のテンス・ムード用法について : 日本語のムードの「タ」との対照を通してモンゴル語の存在・コピュラ動詞のテンス・ムード用法について : 日本語のムードの「タ」との対照を通してAA12516968 Tense and Mood Use of the Existential/Copula Verb in Mongolian : a Comparison with Japanese ta
This paper investigates the mood use, such as “discovery”, “recall”, and “modification of a previous assumption”, of the past forms of the state verb baiqu in Mongolian.
Basically, a non-past form is used when the speaker discovers something without any previous knowledge of it, and a past form is used when confirming/ modifying a prior assumption or an existing knowledge. Bai-jai is usually used for “discovery”,
“recall”, “modification of the speaker’s previous assumption” when the modification itself actually occurs due to the recall. Bai -γsan instead is used in conjunction with other modality affixes, as it owns an adnominal form.
A comparison reveals that in Japanese the past form -ta is used for “actual discovery”, “confirmation of a previous knowledge” and “modification of a previous assumption of the listener”, while in Mongolian the non-past form baiqu is used in the same situations.
