effortful

The word effortful describes something that requires clear mental or physical effort. It often suggests more than simple difficulty: you can feel the work in it. Imagine assembling a complicated piece of furniture without instructions, climbing a long hill, or writing an important email and weighing every sentence carefully. In each case, the action is not smooth or easy; it asks for steady energy and attention.

Effortful is not always negative. Many good things are effortful: studying for an exam, learning an instrument, rebuilding trust, or training for a race. The word often points to the fact that progress, skill, and change take work. An effortful conversation may be emotionally demanding, but it may also help solve a problem.

The word is also used for the way something is done, especially when it seems labored or strained. A doctor might describe breathing, speech, or movement as effortful if it takes unusual exertion. In that sense, the focus is not just on the task itself, but on the visible strain involved in doing it.

In psychology and cognitive science, effortful often refers to processes that need conscious control, attention, or self-control. Resisting a temptation, staying focused on a boring task, or trying to remember a name can all be described this way. So when something takes sustained energy, focused attention, or visibly hard work, effortful is a precise and useful word.
