This tutorial assumes you know basic Hebrew pronouns.
Verbs in Modern Hebrew’s past tense are easy to spot, once you get the hang of it.
A couple of rules of thumb:
- These verbs will have an ending, with the exception of “…הוא” “he…”
- This ending rhymes with the pronoun in the first and second persons – the “I” and “we”, and all the “yous”.
For example: אני התלבשתי – I got dressed, אנחנו התלבשנו – we got dressed. - The endings are either soft-sounding vowels in the third person – just as the pronouns themselves sound soft (היא, הם, הן) – or no ending at all.
For example: היא כתבה – she wrote, הם כתבו – they wrote, הוא כתב – he wrote.
The conversation below features all possible past-tense endings.

But enough theory.
