One of the meaning of the word ‘click’ is to become clear suddenly. It's like when you are solving a problem and suddenly you understood something.

What's the synonyms for this word? Surprisingly I couldn't find anything on Cambridge English Dictionary

  • I find that WordHippo is a useful resource for synonyms of various shades of meaning of a word. Although it doesn't have "a light bulb goes off in (one's) head." Commented Jul 14, 2021 at 11:59
  • Note that many "synonyms" for this metaphoric usage (where click = come together, fall into place = make sense) come at the process from the opposite end. That's to say, rather than it became clear to me, we can say I realised - where the grammatical "subject" is the (concrete noun) person gaining insight, not the (abstract noun) insight itself.

You could say:

  • I understood
  • It became clear
  • it all fell into place
  • The penny dropped (chiefly British idiom)
  • It dawned on me (refers more to having an idea or realisation than understanding)
  • I had a lightbulb moment (usually means having a sudden, good idea)
  • it hit/struck me (a realisation, perhaps upon noticing something)


I found it, from Ancient Greek.

Eureka (Ancient Greek: εὕρηκα) is an interjection used to celebrate a discovery or invention. It is a transliteration of an exclamation attributed to Ancient Greek mathematician and inventor Archimedes.


  • hey downvoter, sour grapes, huh? It's amazing how envy destroys sites like these. That's very often the elephant in the room.

    I'm not the downvoter, but I think the OP needs a verb (X clicked 'X became clear')... Eureka is more of an exclamation. How would you insert Eureka! into that sentence? It Eureka'ed?!

  • @Void There really is no indication that a verb was asked for. But even if they wanted a verb, one can always make it into a verb phrase. This is just plain old pigheadedness or ignorance. :) You suddenly understood something: Eureka! But the Greek expression doesn't require a verb. However, one can be supplied: I had a eureka moment.
