💡 Grammar Points
Masculine Noun Rule
Since 'reino' ends in 'o', it is a masculine word. Always use 'el' or 'un' before it: 'el reino' (the kingdom), 'un reino' (a kingdom).
❌ Common Pitfalls
Confusing Noun and Verb
Mistake: "Using 'reino' when you mean the verb 'to reign' (reinar)."
Correction: Remember 'reino' (noun) is the place. If you want to say 'I reign,' you use the verb form 'Yo reino,' which looks the same but functions differently.

Frequently Asked Questions
Is 'reino' the same as 'monarquía'?
They are closely related. 'Reino' refers to the territory or the political entity itself (the kingdom), while 'monarquía' refers to the system of government where a monarch (king or queen) rules.
Can 'reino' be a verb?
The word 'reino' itself is a noun (kingdom). However, it looks exactly like the 'yo' form of the verb 'reinar' (to reign). So, 'Yo reino' means 'I reign,' but the noun 'el reino' means 'the kingdom.' Context tells you which meaning is intended.
