सावधान (saavdhaan)

adjective/interjection A single core sense meaning 'careful/alert', used both as a descriptive adjective and as a sharp one-word warning or command.
Sense 1 : careful, alert, cautious
adjective Commonly used with रहना (rahnaa) or होना (honaa): सावधान रहना (saavdhaan rahnaa, 'to stay careful/alert') is the standard everyday frame, more so than pairing it with होना (honaa) alone.
Synonyms: सतर्क (satark), चौकस (chaukas), होशियार (hoshiyaar)
Frequency: high
Cultural Note: You will see सावधान (saavdhaan) painted on railway crossing signs and warning boards all over India, often paired with a Hindi-English combo like danger ka nishaan; it carries a slightly formal, public-notice flavor compared to the more casual होशियार (hoshiyaar).
Common Mistakes: 1) Learners often reach for होशियार (hoshiyaar) as a blanket substitute, but सावधान (saavdhaan) leans toward 'being careful/on guard about something specific,' while होशियार (hoshiyaar) leans toward general cleverness or street-smarts -- they overlap but are not always interchangeable. 2) The thing one must be careful of is usually marked with से (se): सांप से सावधान (saamp se saavdhaan, 'careful of the snake'), not किसी को (kisii ko) or a direct object.

Sense 2 : attention! / beware! (as a command)

Cultural Note: This is the word every school student in India has shouted or heard shouted during morning assembly or NCC/parade drills -- सावधान (saavdhaan) and विश्राम (vishraam) are a fixed pair every Indian schoolchild recognizes instantly.
Common Mistakes: Learners sometimes soften this into a polite request in translation ('please be careful'), but as a standalone interjection it functions as a blunt command or alert cry, closer in force to 'Attention!' or 'Watch out!' than to a gentle suggestion.
