Thank you again and again for answering my questions, sir. I'm afraid I have to ask a similar question yet again, though. I just had a recent discussion on FB with friends on the first Filipino gay words we've ever learned. While I was typing my comment, I struggled on whether to use is or was in my sentence "The first Filipino gay word I've learned, found cute, and started using often [is/was] "chorba." Anyway, I ended up using was in that sentence. Was I correct in choosing was or was I wrong? There's one too many was's in that last sentence, no? Also, I am not sure if my use of the past perfect was right or wrong. Would the simple past in such a sentence be more appropriate? I look forward to your reply! Thanks in advance!
Let's take a close look at the sentence you presented:
"The first Filipino gay word I've learned, found cute, and started using often [is/was] "chorba."
It's evident that you've inappropriately mixed tenses in that sentence. You used the present perfect as the blanket tense for the verbs "learn," "find," and "start" despite the fact that they have different times of consummation and duration. The act of learning ends or is consummated upon the acquisition of the knowledge being referred to; finding something is an action that's consummated upon the finding; and starting is an act that's consummated right after the starting action is done. Grammatically, therefore, these three actions shouldn't all be in the present perfect. Instead, they should be presented in different tenses: simple past for "learn," also simple past for "find," and present perfect continuing for "use" as operative verb (not "start"). The correct operative verb for the main clause ("The first Filipino gay word...[is, was] 'chorba'") will then be the present tense "is."
Here then would be the scrupulously correct construction of that sentence:
"The first Filipino gay word I
learned is 'chorba.' I
found it cute and
have been using it often since then.
Note that the sentence has been split into two to indicate that the learning action is separate from the speaker's impression about the gay word and her continuing use of it, and that the adverbial phrase "since then" is supplied to clarify that the speaker have been using that gay word continuously since she simultaneously learned about it and found it cute.
