Learning notes
Explanation
ต่อ has many uses, but the most useful core image is linking something to what comes next. It can mean connecting wires, connecting to the internet, extending a contract, continuing an action, or transferring to another vehicle. As a preposition, it becomes more grammatical: it marks the target of an effect, attitude, or responsibility, and it also marks rates such as “per person” or “per hour.” The noun ต่อ meaning “wasp” is best treated as a separate word with the same spelling and tone.
Usage
ต่อ is common in everyday conversation, travel, shopping, work, study, news, and explanatory writing. In conversation you often hear ทำต่อ, พูดต่อ, and ไปไหนต่อ. In travel, ต่อรถ is common; in shopping, ต่อราคา is useful; in explanations, phrases like ดีต่อสุขภาพ, มีผลต่อ..., and ต่อคน appear frequently.
Caution
ต่อราคา is natural in markets, street stalls, or small shops where bargaining is expected. It can sound odd or rude in fixed-price stores. Also, ต่อ as a preposition is not the normal marker for simply going to a place; use location markers such as ที่ in those contexts.
