mechanically

mechanically — adverb

1. done by a machine or machine parts, rather than by hand or by electronic circuit

1.adverbB1
Definition

done by a machine or machine parts, rather than by hand or by electronic circuits — for example, a factory gate that opens through a system of gears and levers, or a kitchen blender that chops food when you press a button.

Example

The factory gates open mechanically whenever a delivery truck approaches the entrance.

Naoko mixes the paint mechanically by pressing the start button on the electric stirrer.

modifies mixes to show machine-aided operation

Common collocations
  • mechanically operated
  • mechanically driven
  • mechanically powered
  • mechanically controlled
  • mechanically moved
Synonyms
  • by machine

    less formal, used as a phrase rather than a single adverb (e.g. cut by machine)

  • with machinery

    emphasises use of multiple or complex machines rather than a single mechanism

  • power-driven

    focuses on engine or motor power rather than the type of mechanism

Antonyms
  • by hand

    done manually without machine assistance

  • manually

    using human effort rather than a machine

Grammar Patterns

mechanically + verb (e.g. mechanically open)

verb + mechanically (e.g. runs mechanically)

Usage Note

In this sense, mechanically contrasts with electronically or with purely manual action. A device that works mechanically uses physical moving parts such as gears, springs, levers, or belts rather than computer chips or human effort.

Common Mistakes

The door opens mechanically when it detects motion.
The door opens automatically when it detects motion.
'mechanically' refers to physical machine parts (gears, springs); 'automatically' is better for sensor-triggered electronic responses.

2. done as a habit or routine, without paying conscious attention to the task at ha

2.adverbB2
Definition

done as a habit or routine, without paying conscious attention to the task at hand — for example, brushing your teeth while thinking about something else, or nodding along in a meeting you have heard before.

Example

Ramón brushes his teeth mechanically every morning while planning the day ahead.

modifies daily routine to show lack of conscious thought

Padma nodded mechanically as her manager repeated the safety rules for the third time.

Common collocations
  • mechanically nod
  • mechanically answer
  • mechanically repeat
  • mechanically stir
  • mechanically follow
Synonyms
  • automatically

    can also describe programmed electronic responses; broader in scope than mechanically

  • habitually

    focuses on the force of habit rather than the machine-like quality of the action

  • routinely

    more neutral in tone, emphasising that the action is part of a regular procedure

  • mindlessly

    stronger negative tone, implying carelessness or boredom rather than just habit

Antonyms

Grammar Patterns

verb + mechanically (e.g. nodded mechanically)

mechanically + verb (e.g. mechanically repeated)

Usage Note

Frequently appears with verbs of daily routine or work tasks. Unlike automatically, which can describe physical reflexes (blinking, pulling away from heat), mechanically describes actions that were learned through repetition and have become so familiar they no longer require conscious effort.

Common Mistakes

She mechanically blinked when a fly flew past her eye.' (physical reflex)
She automatically blinked when a fly flew past her eye.
'automatically' fits physical reflexes; 'mechanically' is for learned, practiced actions done out of habit.

Synonym discussion

Sense: adverb/2

All four words describe actions performed without full conscious attention, but they differ in tone and scope. Automatically is the broadest: it covers physical reflexes (your hand pulls back from heat automatically) and programmed electronic responses, whereas mechanically is limited to learned routines that run by themselves after enough repetition. Habitually focuses on the force of custom (she habitually checks her phone during meetings) rather than the quality of the action itself. Routinely is the most neutral, describing standard procedure (the crew routinely inspects the engine before each flight). Mindlessly carries a noticeably negative tone — it implies carelessness, boredom, or even foolishness, not just unthinking habit. For example: She mechanically typed the quarterly report (rote, practised action) versus She mindlessly deleted the wrong spreadsheet file (careless mistake with consequences).

Etymology

GreekLatinFrenchEnglish

Formed by adding the adverb suffix -ly to mechanical. Mechanical comes from Latin mechanicus ('belonging to machines'), which was borrowed from Greek mēkhanikos ('inventive, ingenious'), derived from mēkhanē ('device, tool, or contrivance'). The sense of 'done without thinking' emerged in the 1700s from the metaphor of human behaviour mimicking a machine — doing something as automatically as a set of gears turning.
