In Thai language, 'กลับ (glàp)' which translates to 'return' or 'go back' in English, is primarily used to denote a movement back to a prior location or condition. This could refer to a physical return to a specific place, or a return to a previous state or condition. The word ‘กลับ’ is quite flexible in Thai grammar as it can be used with or without prepositions depending upon the actual context.
