Questions & Answers about tā xiànzài dǒng le, wǒ yě dǒng le.

What does the particle 了 do here? Is it just past tense?

No. 了 after 懂 marks a change of state or new situation: “has come to understand / understands now.” It’s not simply past tense. With a stative verb like 懂, 懂了 means the state has newly begun.

Examples:

• 她懂了 = She now gets it (she didn’t before).
• Without 了: 她懂 = She understands (a general fact, not highlighting a change).

Why is 了 used in both clauses? Can I drop one of them?

Each clause has its own predicate, so each uses 了 to mark the new state. If you drop the second 了:

• 她现在懂了，我也懂。 The second clause becomes a general statement (“I also understand (in general)”), losing the “now I get it” feel.
• If you drop both: 她现在懂，我也懂。 You’re simply stating facts, not emphasizing a recent realization.

Using 了 in both keeps the parallel “now-understands” meaning for both subjects.

Where should 现在 go? Can I say 现在她懂了?

Time words usually go after the subject and before the verb: 她现在懂了. Putting it at the very beginning is also fine for emphasis: 现在她懂了. Both are natural. Don’t put 现在 after the verb in this sentence.
