The Spanish word 'dondequiera' (meaning 'wherever') is a compound word formed from two parts: 'donde' ('where') and 'quiera' (a form of 'querer' meaning 'wants' in the subjunctive mood).

The first part, 'donde', comes from the Latin phrase 'de unde', which combined the preposition 'de' ('from') with 'unde' ('whence' or 'from where'). Over time, this Latin phrase evolved into the Spanish word 'donde'.

The second part, 'quiera', derives from the Latin verb 'quaerere' meaning 'to seek' or 'to want', which evolved into Spanish 'querer' ('to want'). When these two elements combined, they formed 'dondequiera', literally meaning 'where(it)wants' but used to mean 'wherever' in Spanish.

Several common Spanish words are related to 'dondequiera'. The simpler word 'donde' meaning 'where' is obviously related as it's the first part of the compound word. The very common verb 'querer' ('to want') is related to the second part 'quiera'. Understanding these connections can help you remember that 'dondequiera' is essentially combining the concepts of 'where' and 'wanting' to create the meaning of 'wherever'.

While there aren't many obvious English cognates for 'dondequiera', the Latin root 'quaerere' (meaning 'to seek' or 'to want') has given English some related words. For example, 'query' (to ask or question), 'quest' (a search or pursuit), and 'inquire' (to ask about) all come from this same Latin root. These words all share the basic concept of seeking or wanting information, similar to how 'querer' in Spanish expresses wanting or desiring something.
