Use of the progressive aspect or 'continuous' tense, in situations where standard English uses a simple one, is a very notable feature of Indian English and one which is immediately obvious to non-Indian speakers.
Some linguists suggest that this may be due to the way verbs are formed in Hindi/Urdu:
6.2.3 Habitual and progressive aspect in Hindi/Urdu
The complex aspect system of Hindi/Urdu contains both continuous tense
forms for actions or states that are incomplete and in progress, and
habitual tense forms for actions or states which occur generally or
regularly (...).
The distribution and usage
resembles the English system, so that the forms translate relatively
easily into English. The most striking feature in verb formation in
Hindi/Urdu is the existence of compound verbs, i.e. verb forms
composed of two usually finite verbs or a verb and a noun. Examples of
the formation of these verbs (...) are
pəsənd hona "liking be" = to like
svikar kərna "acceptance do" = to accept
[A linguist] suggests that because verbs such as hear and see can be
used in the progressive form in Hindi/Urdu, a process of
transfer/interference can account for the Indian English use of
otherwise stative verbs in the progressive.
