What does tweak mean?
Tweak is a familiar verb and noun for making a small adjustment to something. As a verb, it means to alter or refine a detail without changing the basic form or purpose: a designer may tweak a layout, or a programmer may tweak the settings of an application. As a noun, “a tweak” denotes the minor modification itself, as in a final tweak to the schedule. The word often conveys repeated, careful tinkering rather than a fundamental revision, though the distinction can depend on context. Tweak can also mean to twist or pull sharply, but that older sense is much less common in modern English. In computing, photography, design, and everyday informal speech, “tweak” is especially useful because it captures a small change that improves or fine-tunes a larger thing without suggesting wholesale replacement. British and American usage are broadly alike. Its everyday familiarity contrasts with its older history: the word originally concerned pulling or twisting before developing the modern sense of minor adjustment.
To alter or adjust something in a small, subtle, or incremental way.
"We tweaked the code to improve its performance on smaller devices."
Widely used in technical and informal contexts; it generally implies modification without replacing the underlying thing.
A small modification or adjustment made to something.
"The final version required a few minor tweaks."
Common in general, technical, and creative contexts. The plural “tweaks” is usual when several separate adjustments are made.
The plural is used for multiple small modifications or adjustments.
"The designer made a series of subtle tweaks to the layout."
Tweak began as a word for pulling or twisting; its modern fame comes from doing the opposite—changing only a tiny detail.

Where does tweak come from?
The modern word developed from Middle English twikken, meaning “to pull, pluck, or twist,” probably continuing Old English twiccan, with related forms found in words such as twitch and German zwicken, meaning “to pinch.” The verb’s longstanding association with manipulating or pulling something helped lead to the later sense of making a slight adjustment. The precise development of the modern form is not entirely certain.
