Past Continouns Tense

Remember in this Tense, I was (in English) = I had (in Persian)

Let's translate " I was writing"
1. First, change verb "have"
to have = داشتن /da:shtan/
Delete ن /nu:n/, = داشت /da:sht/

Now, try to use داشت with all subjective pronouns in Simple Past Tense:
I had = من داشتم /man da:shtam/
You had = تو داشتي /to da:shti/
He had = او داست /u: da:sht/
We had = ما داستيم /ma:da:shtim/
You had = شما داشتيد /shoma: da:shtid/
They had = انها داشتند /a:nha: da:shtand/


2. then, change the main verb " write"
to write = نوشتن /neveshtan/
Delete ن /nu:n/, = نوشت /nevesht/

I wrote = من نوشتم /man neveshtam/
You wrote = تو نوشتي /to neveshti/
He wrote = او نوشت /u: nevesht/
We wrote = ما نوشتيم /ma: neveshtim/
You wrote = شما نوشتيد /shoma: neveshtid/
They wrote = انها نوشتند /a:nha: neveshtand/

put مي /mi/ before the main verb, so,
I was writing = من داشتم مي نوشتم
You were writing = تو داشتي مي نوشتي
He was writing = او داشت مي نوشت
We were writing = ما داشتيم مي نوشتيم
You were writing = شما داشتيد مي نوشتيد
They were writing =انها داشتند مي نوشتند
