'Tis sooner said than done.

Understand the thought

Meaning in plain English

Describing an action can be much easier than carrying it out. Consider the effort, resources and difficulties behind a proposal before treating a simple instruction as a complete solution.

What the words are saying

The comparison separates the ease of saying what should happen from the work of making it happen. A short proposal may conceal several dependent tasks or ignore circumstances faced by the person expected to act. The proverb can temper an oversimplified suggestion and invite a more workable plan. It does not make discussion useless or show that a task is impossible merely because it is difficult. Clear words can be the beginning of useful action. The practical next question is what the proposal requires, who can do it and which obstacles need attention rather than another repetition of the instruction.

Everyday example

Instead of only telling a group to make an exhibition accessible, an organiser checks the route, information format and support required to put that instruction into practice.

When to use it

Use it when an apparently simple suggestion has overlooked the work needed to implement it.
