Morse code mnemonics are systems to represent the sound of Morse characters in a way intended to be easy to remember. Since every one of these mnemonics requires a two-step mental translation between sound and character, none of these systems are useful for using manual Morse at practical speeds. Amateur radio clubs can provide resources to learn Morse code.

In Czech, the mnemonic device to remember Morse codes lies in remembering words that begin with each appropriate letter and has long vowel (i.e. á é í ó ú ý) for every dash and short vowel (a e i o u y) for every dot. Additionally, some other theme-related sets of words have been thought out as Czech folklore.

In Polish, which does not distinguish long and short vowels, Morse mnemonics are also words or short phrases that begin with each appropriate letter, but dash is coded as a syllable containing an "o" (or "ó"), while a syllable containing another vowel codes for dot. For some letters, multiple mnemonics are in use; the table shows one example.
