「Adjectives and Adverbs」
「Expressions Following Adjectival Predicates」
In Japanese, when using adjectival predicates in the present, past or negative forms, they are combined with other elements such as auxiliaries, particles, or phrases to create various expressions.
「Adj pred + darō・だろう」
Is/was probably cold
Tekisetsu*/Tekisetsu datta darō
Is/Was probably appropriate
「*Da・だ is dropped」
Darō, the presumptive form of the copula (be-verb) da, is used as an auxiliary to indicate conjecture of the speaker. Deshō is the polite form of darō.
Umi no mizu wa tsumetai darō.
The ocean water is probably cold.
Shiga Kōgen wa suzushikatta deshō.
The Shiga Highlands were probably cool.
Isha no shochi wa tekisetsu datta deshō。
The doctor's treatment was probably appropriate.
