Tense and Verb Form Errors

Tense errors in SBI Clerk are almost always about consistency: a sentence must stay in one time frame unless a signal word forces a shift. Answer first — spot the time marker, decide the tense it demands, then check every verb obeys it. The paper plants a wrong tense that clashes with a clear clue such as 'yesterday', 'since 2010' or 'by the time'. Once you learn to read these signal words, the correct verb form is fixed for you and guessing disappears from your approach.

Keep One Time Frame

Within a single sentence the tenses should agree unless meaning requires a change. 'He came home and drinks water' is wrong because came is past but drinks is present; it should be 'came home and drank water'. When a main clause is in the past, the subordinate clause usually follows into the past too. Scan for a verb that suddenly jumps time with no reason, and that verb is your error nine times out of ten.

Since, For and the Perfect Tense

'Since' points to a starting point in time and 'for' points to a length of time, and both usually demand a present perfect verb. 'He has worked here since 2015' and 'He has worked here for eight years' are both correct, but 'He works here since 2015' is wrong. The moment you see since or for with a duration, expect has or have plus the third form, and reject a plain present tense verb straightaway.

Had + Third Form for the Earlier Past

When two past actions happen at different times, the earlier one takes past perfect — had plus the third form. 'The train had left before we reached the station' is correct because leaving happened first. A common trap writes 'had went' or 'had ran'; the third form must follow had, so it is 'had gone' and 'had run'. Whenever you see 'before', 'after' or 'by the time' linking two past events, check that the earlier action uses had correctly.

Solved Examples

Example 1: 'She is living here since 2018.' The clue since needs present perfect continuous. Corrected: 'She has been living here since 2018.'

Example 2: 'When I reached, the film already started.' Two past actions need past perfect for the earlier one. Corrected: 'When I reached, the film had already started.'

✗ He did not went to office yesterday  |  ✓ He did not go to office yesterday

The Speed Shortcut

Do not read a tense sentence for grammar; read it for one signal word and let that word dictate the answer. Sweep the sentence for a time marker — since, for, ago, already, by the time, before, after — and the instant you find one, you already know the required tense before checking any verb. If the marker is since or for, the answer involves has or have. If two past actions are linked by before or by the time, the earlier one needs had plus the third form. If a helper verb like did, does or will appears, the main verb must return to its base form, so 'did not went' is always wrong. This clue-hunting reflex turns tense questions into a lookup rather than an analysis, which is exactly what a 34-second-per-question paper rewards.
