What does autocomplete mean?
Autocomplete is a computing term for a software feature that anticipates what a user is typing and offers to complete it automatically. When someone begins entering a word, name, search query, or web address, the system draws on stored data or common patterns to suggest likely endings, which the user can accept with a single keystroke or tap. The word also works as a verb, as in 'the form autocompleted my address.' Familiar from search engines, web browsers, code editors, and smartphone keyboards — where related features include predictive text and autocorrect — autocomplete has become one of the most visible examples of predictive software in everyday life. Its connotations are largely positive: speed, convenience, and reduced typing effort. At the same time, it raises questions about privacy and influence, since the suggestions a user sees can shape what they search for or say. The term is neutral in register and universally understood among people who use digital devices.
A software feature that predicts and offers completions of a word, phrase, or query while the user is still typing.
"The autocomplete in the search bar guessed her destination city after just two letters."
Countable and uncountable; often preceded by 'the'. Related but distinct from autocorrect.
To complete text, a form entry, or a query automatically using a predictive feature.
"The app autocompleted his home address the moment he typed his postcode."
Rarely used in the plural; the noun usually appears in the singular or uncountably, referring to the feature generally.
"Different browsers handle their autocompletes in slightly different ways."
Google once reported that roughly one in four of its search queries were completed by autocomplete — the feature finishes our thoughts so often it has quietly become an editor of what we ask.

Etymology of autocomplete
Autocomplete is formed from the Greek-derived prefix 'auto-' meaning 'self' or 'spontaneous', combined with 'complete', which comes from Latin 'complere', meaning 'to fill up' or 'finish'. The compound follows a productive English pattern seen in words like autofocus and autopilot. It emerged in the late twentieth century alongside interactive computing, as text editors and command-line interfaces began finishing users' input automatically, and entered widespread everyday use with the rise of search engines and mobile keyboards.
How autocomplete is actually used
Predominantly a technical term from computing, now widely familiar to general users through smartphones, browsers, and search engines. It functions as both noun ('the autocomplete') and verb ('to autocomplete'). The hyphenated form 'auto-complete' appears occasionally but the solid form is standard. Informal-to-neutral register; not used in literary prose except when discussing technology.
Easily confused with autocomplete
Autocomplete suggests how to finish a word or phrase you are typing, while autocorrect automatically replaces what you have typed with a corrected spelling.
