English dictionaries translate ばかり as "just (finished, etc.)" but that doesn't
seem to really work because "I just came" is past tense and "私は来たばかりだ" is
present tense. ばかり is an adverbial particle in the same vein as だけ and まで, but
I don't see how ばかり modifies だ. An

in a Japanese dictionary describes it as 動作が完了してまもない状態にある意を表す, but that
doesn't really tell what the meaning of だ is in those sentences since the
meanings of ある and だ are quite different. Is だ in たばかりだ sentences being used
the same way as in 私は先生だ (noun) or 私は静かだ (adjective)? Since ばかり is an
adverbial particle and not something that can connect だ with a noun, I am
confused.

question
grammar meaning
What is the meaning of だ when used in a sentence involving a past tense verb like 来たばかりだ?
ばかり is one of those words that doesn't work very well as an English part of
speech. A translation of these phrases gets the meaning across, but it does
not represent the structure of the Japanese at all. But if it helps, think of
it this way: saying "来たばかりだ" means "the current situation is that I have just
arrived." If you said "来たばかりだった," that would mean "a situation in the past was
that I had just arrived"; the meaning becomes pluperfect since you're talking
about something that had already happened at an earlier point in time.

For a more rigorous explanation, let's break down the sentence: 私は来たばかりだ into
parts.

私は: I-topic/as for me

来たばかり: came-just (just came)

だ: copula/it is (that)

So if you wanted to go for a really liberal translation, you could argue it
says, "it is that I just came," where "it" refers to the general situation or
something similarly ambiguous. I feel like I could have explained this better,
but I hope that helps.
