Solitário vs. sozinho vs. só
The Portuguese words solitário, sozinho, and só may all relate to the ideas of being alone, lonely, or solitary, but their usage, connotation, and grammatical function differ significantly. Understanding these distinctions is key to choosing the right word in different contexts.
Solitário
B1Solitário emphasizes a state of being or lifestyle that is marked by solitude or isolation, often with a connotation of loneliness but not exclusively. It is primarily an adjective and less frequently a noun.

Sozinho
A2Sozinho refers to a state of being alone physically or emotionally, and it is used as an adjective or adverb. It can describe someone who is by themselves, either by choice or circumstance, without necessarily carrying a tone of sadness or isolation.
Estou sozinho em casa hoje à noite.
(I am alone at home tonight.)

(He solved the problem by himself, without help.)
Você não está sozinho nessa luta.
(You are not alone in this struggle.)
Só
A1Só is more versatile, serving as both an adverb and an adjective. As an adverb, it can mean only or just. When used as an adjective, it means alone or by oneself, often interchangeably with sozinho, but tends to suggest a more casual tone.
Fiquei só em casa enquanto todos saíram.
(I stayed alone at home while everyone went out.)
Eu só queria te ajudar.
(I just wanted to help you.)

(Walking alone at night can be dangerous.)
Summary
Solitário, sozinho, and só have overlapping meanings related to being alone, but their usage and nuances are distinct. Solitário focuses on a solitary lifestyle or state, often emotional or descriptive. Sozinho emphasizes being physically or emotionally alone, often neutral or descriptive of independence. Só is versatile, functioning as an adverb meaning only or just and as an adjective similar to sozinho but with a more informal tone. Choosing the correct word depends on context and desired emphasis.
