Verbs express when something happened, or that something is continuing or finished. Verbs help people make sense of other parts of a sentence or clause.
Verbs describe an action, a state, an event or a change
Verbs are words that describe:
- an action
- a state
- an event
- a change.
to result in[events]
The form of the verb changes depending on the grammatical subject and tense.
Verbs must ‘agree’ with the subject
The form of the verb changes to show whether the subject is singular or plural (the number). This is called ‘subject–verb agreement’.
works in the office on Mondays. [There is one specific analyst, so the verb takes the singular form ‘works’.]
work in the office on Mondays. [There is one person, Jan, so the verb should not take the plural form ‘work’.]
To decide which form of the verb you need, find its subject and ask ‘who’ or ‘what’ is doing the verb. Using the first example:
- Question: Who works in the office on Mondays?
- Answer: The analyst.
This answer might seem obvious, but subject–verb agreement is not always intuitive. For example, a common mistake is to use the plural form of a verb with a collective noun.
Sentences contain at least a subject and a verb. Keep the relationship between the grammatical subject and the verb clear to users. This relationship is the basis for writing plain language sentences.
Objects complement some verbs
Some verbs need an object to have meaning. For example, you don’t just need or take – you need ‘something’ or take ‘something’. These are ‘transitive’ verbs.
needadvice before the hearing. [‘Advice’ is the object of the verb ‘need’.]
Takemy advice. [‘My advice’ is the object of the verb ‘take’.]
- The power grid
failed. [The verb ‘failed’ does not have an object.]
- The candidate
campaignedtirelessly. [The verb ‘campaigned’ does not have an object. ‘Tirelessly’ is an adverb. The adverb complements the verb.]
Some verbs can be transitive or intransitive. They can have meaning with or without an object, depending on the rest of the sentence.
openedthe door. [The object is ‘the door’.]
- The door
opened. [‘Opened’ has no object.]
A complement can go with a verb that links the subject to an attribute, quality or characteristic. This type of complement is not an object, but completes the sentence. They are often adjectival phrases or adjectives.
- The door is
open. [‘Open’ complements the verb ‘is’. It is an adjective that describes the subject, ‘the door’.]
- The forecasts seem
reasonable. [‘Reasonable’ complements the verb ‘seem’. It is an adjective describes the subject, ‘the forecasts’.]
- Each agency has
its own arrangements. [‘Its own arrangements’ complements the verb ‘has’. The complement is a noun phrase describing an attribute of the subject, ‘each agency’.]
Tense changes the form of the verb
The form of the verb can also change to show:
- when something happened (past, present or future) – this is the tense of the verb
- whether something is continuing or has finished.
was writingthe report last week, but I couldn’t finish it. [The action is in the past tense and is continuing. I didn’t finish writing the report last week.]
wrotethe report yesterday. [The action is in the past tense and has finished.]
am writinganother report today. [The action is in the present tense and it is continuing.]
will writea final report tomorrow. [The action is in the future tense and it will be finished tomorrow.]
- By next week, the executive
will have reviewedthe report. [The action is in the future tense and will be finished by next week.]
Verbs like ‘will’ change the form of the main verb ‘to write’. Verbs added to the main verb are ‘auxiliary’ verbs.
The ‘mood’ of a verb conveys meaning
You can use verbs to describe a fact, express a wish, or make a command or request. The term for this use is ‘mood’.
This mood expresses simple statements or questions.
wentinto the office on Monday.
- The commander
orderedthe troops to stand at ease.
tabledin July this year?
This is the mood for expressing urgency, commands, pleas and requests.
The imperative mood is direct. It works well for instructions and where there is limited space, such as in forms.
Lodgeyour submission by 31 July.
Verifyyour corporate credit card.
Be deliberate about the tone the content needs to convey. Imperative commands can seem blunt, even if you use the word ‘please’.
This is the mood for expressing possibility. It shows that something is hypothetical, possible, conceivable or desirable.
- If supply
were to stop, we
wouldn’t be ableto meet demand.
- If only they
would updatethe data!
Verbs in the subjunctive mood can work together with other words to express a condition.
- If you
tooka sample, you
would havesome data.
- If you
could processyour application tomorrow.
The subjunctive mood doesn’t always need an auxiliary verb to show the mood, only the main verb. Recommendations can follow this formula.
- That the Minister
meetwith peak body representatives.
You can use auxiliary verbs to convey ability, possibility, permission or obligation. This affects the tone of your writing.
These verbs are:
- ought to.
couldtake some time.
mustsubmit your application by close of business.
Phrasal verbs need a preposition or adverb
- We need to
check in witheach other. [The verb ‘check’ pairs with the prepositions ‘in’ and ‘with’.]
found out6 breaches had occurred. [The verb ‘found’ goes with the adverb ‘out’.]
When phrasal verbs need an object, you can put the object between the verb and its other part.
gave away the answer. [The object, ‘the answer’, comes after both parts of the phrasal verb, ‘gave away’.]
gave the answer
away. [The object comes between the first and second part of the phrasal verb.]
The digital edition relates grammatical concepts to the principles of plain language. It relates word choice to grammatical information about types of words.
It provides an overview on types of words to introduce grammatical concepts about parts of speech and how they relate to sentence structure.
The sixth edition called types of words ‘word classes’. It had summary information about parts of speech on pages 68 to 70. This formed part of Chapter 5 on grammar.
The Content Guide did not have any in-depth information on grammatical concepts.
