requiring a lot of hard work
Needing a lot of time and hard work, and often feeling slow or difficult.
Usage pattern:
a laborious [task/process/journey]; [doing something] is laborious
Common mistake:
Learners sometimes use *laborious* to describe a person (e.g., "a laborious worker"), but in modern English it almost always describes activities or processes, not people. Use "hardworking" for a person and "laborious" for the task: "She is a hardworking employee, and the project is laborious." Learners may also confuse *laborious* with *labor* meaning childbirth; these are related in origin but used in very different contexts.
Synonyms
arduous (Stresses great physical or mental effort; often a bit stronger and more dramatic than "laborious.")
|
taxing (Emphasizes how tiring and demanding something is, sometimes emotionally or mentally.)
|
strenuous (Often used for physical effort; suggests intense exertion more than slowness.)
|
tedious (Focuses more on something being boring and repetitive than on actual amount of effort.)
Antonyms
easy (Describes something that does not need much effort or skill, the direct opposite of "laborious.")
|
effortless (Suggests something is done with almost no visible effort, the strong opposite of "requiring much effort.")

overly careful, heavy in style
Describes writing, speaking, or thinking that feels slow and heavy because the person is trying too hard.
Usage pattern:
laborious [style/prose/explanation]; a laborious attempt to [do something]
Common mistake:
Learners sometimes think *laborious* here means only "boring." While it can feel boring, the key idea is that the writer or speaker is trying too hard, so the result is slow, heavy, and awkward. For simple "boring," words like "dull" or "uninteresting" are better.
Synonyms
clumsy (Suggests the style is not smooth or natural; less formal than "laborious.")
|
ponderous (Emphasizes that the style feels heavy and slow, often long-winded.)
|
stilted (Focuses on speech or writing that sounds unnatural or too formal; overlaps with the awkward side of "laborious.")
Antonyms
fluent (Describes speech or writing that flows easily and naturally, opposite of slow and effortful.)
|
lively (Emphasizes energy and ease in writing or speech, contrasting with the heavy, slow feeling of "laborious.")

slow, effortful movement or breathing
Describes movement or breathing that is slow and hard because it needs a lot of effort.
Usage pattern:
laborious breathing; laborious [movement/progress/steps]
Common mistake:
Learners may mix up *laborious* and *labored* for breathing. Both can be used, but *labored breathing* is more common in everyday and medical English. *Laborious* here sounds a bit more formal or literary.
Synonyms
labored (Very close in meaning, especially for breathing; slightly more common in everyday and medical description.)
|
painful (Highlights the discomfort or pain involved in the movement or breathing, not just the effort.)
Antonyms
easy (Describes movement or breathing that happens without much effort or discomfort.)
|
smooth (Emphasizes movement or breathing that is regular and without difficulty, opposite of strained or heavy.)
Collocations

|laborious progress
|laborious steps
