English has 12 verb tenses, and once you see the pattern behind them they stop feeling like 12 separate rules and start feeling like one simple grid. Every tense answers two questions: when does the action happen (past, present, future) and how do we view it (simple, continuous, perfect, or perfect continuous)? Master those two ideas and you master all twelve.
The two questions behind every tense
Think of a 4×3 grid. The three columns are past, present, and future. The four rows are simple (a fact or habit), continuous (action in progress), perfect (action completed and connected to another point in time), and perfect continuous (a duration leading up to a point). Combine a column with a row and you get a tense.
The simple tenses
- Present simple:
She works in Berlin.Use it for facts, habits, and routines. - Past simple:
She worked late yesterday.A finished action at a known time in the past. - Future simple:
She will work tomorrow.A decision, prediction, or promise.
The continuous (progressive) tenses
Continuous tenses use be + verb-ing and describe an action in progress at a moment in time.
- Present continuous:
She is working right now. - Past continuous:
She was working when I called. - Future continuous:
She will be working at 9 p.m.
The perfect tenses
Perfect tenses use have + past participle and link two points in time — they tell you something was completed before another moment.
- Present perfect:
She has worked here for five years.Started in the past, still relevant now. - Past perfect:
She had worked there before she moved.The “earlier past.” - Future perfect:
She will have finished by noon.Completed before a future point.
The perfect continuous tenses
These combine duration with completion, using have been + verb-ing.
- Present perfect continuous:
She has been working all day. - Past perfect continuous:
She had been working for hours before the break. - Future perfect continuous:
By May she will have been working here for a decade.
The mistakes learners make most
- Present perfect vs. past simple. Use the past simple with a finished time (
yesterday,in 2020) and the present perfect when the time is unfinished or unspecified (already,ever,so far). - Overusing the continuous with stative verbs. Verbs like
know,believe, andownusually stay simple: sayI know, notI am knowing. - Forgetting time markers. Words like
since,for,already, andyetare strong signals for which tense to choose.
