Why only stemming verbs?

[kavitharaju]

Is it because Bengla has more suffixes for verbs ?
And other words like nouns, adjectives and adverbs do not have suffix modifications in Bengla?
(I do not know the language, but was interested in your project for text processing). Thanks

I am sorry for the late reply @kavitharaju. The project went inactive for a while. We are back up again!
