Sentence Error

The sentence provided for analysis is: He is living in Chennai since five years. The objective is to pinpoint the specific segment containing a grammatical mistake.

'since five years' Error

The primary grammatical error is located in the phrase 'since five years'. This mistake arises from the incorrect use of the preposition 'since'.

Rule Recap:

• 'Since' denotes a specific starting point in time (e.g., 'since yesterday', 'since 2021').
• 'For' indicates a period or duration of time (e.g., 'for two days', 'for three months', 'for ten years').

As 'five years' represents a duration, the correct preposition should be 'for'. The correct phrasing is 'for five years'.

'living' Verb Tense

Additionally, the verb tense used might not be the most appropriate for the context.

• The present continuous tense ('is living') usually describes actions happening right now or temporary situations.
• For actions that commenced in the past and continue to the present, the present perfect continuous tense ('has been living') is generally preferred to emphasize the duration and continuity.

Therefore, a more standard construction would be 'He has been living in Chennai for five years.'
