Common English Expressions for Functions

A function is a countable noun, so when mentioning a single function for the first time in a general context or conversation, you use the article a to say a function.

When referring to multiple functions, you should use the plural form, functions.

Conversely, when referring to a function that both the speaker and the listener are familiar with, or a function with specific uniqueness, use the article the to say the function or the functions.

To effectively implement a function that performs a specific task and describe it accurately, it is important to use appropriate verbs and prepositions in context.

Prepositions can often be tricky as their meanings are not always clear-cut, which can be particularly confusing for non-native English speakers.

For example, when passing arguments to a function, rather than using verbs like 'deliver' or 'give,' you should use pass. The preposition used before the function should be to, not 'on' or 'for.'
