The Spanish word 'alemán' (meaning 'German') comes from the French word 'allemand', which in turn derives from the Latin 'Alamannus'. This Latin term referred to the Alamanni, a confederation of Germanic tribes. The word 'Alamannus' itself is composed of two Germanic elements: 'all' meaning 'all' and 'mann' meaning 'man'. Thus, the original meaning was something like 'all men' or 'all people', which became the name used to refer to these Germanic peoples and eventually came to mean 'German' in several Romance languages.

In Spanish, 'alemán' doesn't have many etymologically related simpler words, as it was borrowed as a complete term to specifically refer to German people and their language. However, you might see it in compounds like 'germano-alemán' (German-Germanic) or in the feminine form 'alemana'.

While English uses 'German' rather than a word related to 'alemán', we can see connections to the Germanic roots of 'alemán' in English words. The Germanic element 'mann' is clearly related to English 'man', and 'all' is identical to the English word 'all'. While these words aren't used together in English to mean 'German', understanding these components can help remember that 'alemán' originally meant something like 'all men' or 'all people'.
