Finite Verbs versus Verbals
- How it worksHow do you spot the single word in a clause that is marked for time and tied to a doer?
- Worked exampleWalk me through labelling every verb form in 'Hoping to finish, the crew working through the night.'
- Common mistakeWhy isn't 'running' a verb in 'The stream running past the cabin' when it clearly describes an action?
- Going furtherWhat happens to that same phrase the moment you insert the word 'is' in front of 'running'?
The Sentence With No Main Verb at All
- How it worksHow do you audit a twenty-word sentence for the one word that is carrying the tense?
- Worked exampleShow me what is missing from 'The observatory, built in 1897 and restored twice since, on a ridge above town.'
- Common mistakeWhy doesn't a participle like 'built' count as the verb that finishes a sentence?
- Going furtherWhat happens to a verbless sentence the moment you convert one of its participles into a tensed verb?
Gerunds, Participles, and Infinitives
- How it worksHow do you tell a gerund from a participle by looking at the job the word is doing?
- Worked exampleWalk me through labelling 'swimming' in 'Swimming builds endurance' and in 'The girl swimming laps is my sister.'
- Common mistakeWhy isn't every -ing word a gerund, given that a participle wears exactly the same ending?
- Going furtherWhat happens when an infinitive like 'to finish' tries to serve as the main verb of a sentence?
Having Mapped versus Mapped
- How it worksHow does 'having finished' mark an action as already over before the main clause even begins?
- Worked exampleShow me the time order inside 'Having mapped the cave, the team published its survey.'
- Common mistakeWhy isn't 'having mapped' ever the main verb of the sentence it opens?
The Simple Tenses on a Timeline
- How it worksHow do past, present, and future put one event at three different points on a single line?
- Worked exampleFind the tense error in 'Last winter the harbor freezes and the ferries stop for a month.'
- Common mistakeWhy isn't the present tense a claim about this exact moment in 'Iron rusts when it meets damp air'?
The Progressive Aspect
- How it worksHow does a form of 'be' plus an -ing verb turn an action into something still underway?
- Worked exampleWalk me through why 'The glacier was retreating when the survey began' nests one event inside another.
- Common mistakeWhy doesn't the progressive belong on a verb like 'know' or 'belong' that names a state rather than an action?
- Going furtherWhat happens when a writer uses a progressive verb for a permanent fact like a mountain standing?
The Perfect Aspect
- How it worksHow does the present perfect draw a bridge from a point in the past all the way to now?
- Worked exampleShow me what the timeline does differently for 'She worked here ten years' and 'She has worked here ten years.'
- Going furtherWhat happens to the perfect when its helping verb moves into the future as 'will have'?
- Common mistakeWhy doesn't 'has taught' mean the same thing as 'taught' when both describe years already gone?
The Past Perfect and the Earlier Past
- How it worksHow does the word 'had' pin one event to the left of another event already sitting in the past?
- Common mistakeWhy isn't 'had' correct in every past sentence simply because the event happened a long time ago?
- Worked exampleWalk me through repairing 'When the archivist opened the box, someone already removed two of the letters.'
- Going furtherWhat happens to 'had' once the sentence already states in plain words which event came first?
Sequence of Tenses Across Clauses
- How it worksHow does pushing 'said' into the past reach inside the reported idea and shift its verb as well?
- Worked exampleWalk me through why 'She announced that she will resign' becomes 'would resign' in a past-tense report.
- Common mistakeWhy isn't forcing every verb in a sentence into one tense a safe way to dodge a sequence error?
- Going furtherWhat happens to that rule when the reported clause states something that is still true today?
Tense Consistency in a Narrative
- How it worksHow does one governing tense set a default that every other verb has to justify leaving?
- Worked exampleShow me which verb breaks the pattern in 'The hikers set out at dawn, cross the ridge, and camped by the lake.'
- Common mistakeWhy isn't every tense change inside a paragraph an error, given that time itself keeps moving?
- Going furtherWhat happens when a passage about a long-dead author switches to the present to describe their book?
