Bengali Language/Expressing Obligation with Verb

Expressing obligation requires a few transformations.

Step 1

edit

The person who is obliged to do things cannot be grammatically represented in the typical Subject Pronoun form, but in the Possessive Pronoun form in the following way :

Person and
Number

Step 2

edit

Take the infinitive form of the verb denoting the activity that one is obligated to do. Add the modal word উচিত uchit right after it, like in the following table :

Infinitive Obligation expression
(person/number independent)
বলা
bawlaa
"to say"
বলা উচিত
bawlaa uchit
"must say"
করা
kawraa
"to do""
করা উচিত
kawraa uchit
"must do"
খাওয়া
khaawaa
"to eat""
খাওয়া উচিত
khaawaa uchit
"must eat"

The word উচিত uchit is a modal word which means "obligation" or "must". Note that this obligation expression is person and number independent. It doesn't change according to who is doing something or how many people are doing something.

Step 3

edit

Now combine the possessive form and the obligation expression to make a full obligation statement, like in the following

Possessive
pronoun form
Obligation

(without object)
আমার
aamaar
"my"
বলা উচিত
bawlaa uchit
"must say"
আমার বলা উচিত
aamaar bawlaa uchit
"I must say"
তোমার
tomaar
"your""
করা উচিত
kawraa uchit
"must do"

tomaar kawraa uchit
"You must do"
তার

"his/her""
খাওয়া উচিত
khaawaa uchit
"must eat"

taar khaawaa uchit
