Tense and aspect

What follows refers only to English.  Languages deal with these two issues very differently indeed.

What's the difference between Tense and Aspect?

Tense refers to the time of an event and is often marked by a change in the verb ending.  So we have, e.g.:

  1. Rita believes in ghosts (present)
  2. Rita believed in ghosts (past)

In fact, unlike most languages, English also has no inflexion on the base form of the verb in many cases (They believe in ghosts) but it is still a present tense.
Arguably, English has no future tense because we don't have a form of the verb to signify future time.  We denote the future in many ways – She is going to talk to me, She will talk to me etc.  More of that later.

Aspect refers to how an event or state is perceived with reference to time.  So we have, e.g.:

  1. Rita has broken the rule
  2. Rita is breaking the rule

Sentence 3 tells us not only that the rule was broken in the past but also that it has some relevance to the present.  The fact that she has broken the rule will have consequences now.
Sentence 4 gives a different aspect.  The -ing ending on the verb is called a present participle ending and in English that tells us that the event is happening now.  Unfortunately, English present tenses are a bit complicated.  Think what these actually mean and then click here for the answers.

  1. Rita walks to school
  2. Rita is walking to school tomorrow
  3. Rita is walking to school now

Aspect and tense are very closely related.  We can use other tenses with progressive (be + -ing) aspects and with perfect aspects (have + the past participle of the verb).  Here are two examples:

  1. Rita had walked to school (perfect aspect, past tense – we call this the past perfect tense)
  2. Rita was walking to school (progressive aspect, past tense – we call this the past progressive tense)

Before we go on, here's a summary of the all the present and past tenses and aspects with their names, along with the future forms English also uses.

Example (form in italics) Tense name
She often speaks to her boss Present simple (habit)
She is speaking to her boss Present progressive
She spoke to her boss Past simple
She was speaking to her boss Past progressive
She has spoken to her boss Present perfect
She has been speaking to her boss Present perfect progressive
She had spoken to her boss Past perfect
She had been speaking to her boss Past perfect progressive
She will speak to her boss Future simple (factual future)
She is speaking to her boss tomorrow Present progressive (future)
She is going to speak to her boss 'going to' future (intentionality)
She will be speaking to her boss Future progressive (ongoing future)
She will have spoken to her boss Future perfect (past in the future)
She will have been speaking to her boss Future perfect progressive (past in the future)
