The phrase 'ไม่แค่...แต่ยัง... (mâi khâe... dtàe yang...)' is commonly used in Thai to express 'not only... but also...'. This structure helps add depth and emphasis to statements by expressing that not only is the first part of the statement true, but the second part is additionally true, often in a surprising or unexpected manner. It is versatile, and can be used with a variety of verbs, adjectives, and phrases.
