Traditional studies on tenses in complex sentences have referred to the tense marking in the subordinate clause as 'relative tense,' distinguishing it from the 'absolute tense' indicated by the matrix predicate (see for example Terarnura 1984).
although in (20) the embedded clause nai-te iru (is crying) is by default interpreted in relation to the tense of the matrix predicate, it can be extended with adverbials such as ima (now) and asoko de (over there) that make a reading more reasonable in which the embedded tense is interpreted in relation to the utterance time.
