这么

so
这 (this) + 么 (suffix) — literally 'this-way'
这 means 'this' and 么 is a common adverbial suffix (also in 那么 'that way', 怎么 'how'). So 这么 = 'this way / so / such'. Pronounced zhème, often reduced to zhèmo in speech.
这 — walk radical 辶 + speech 言
这 is the simplified form of 這. The traditional character combines the walk/movement radical 辶 with 言 (speech), originally meaning 'to meet' or 'to encounter on the way.' Over time it shifted to function as the demonstrative 'this,' likely through phonetic borrowing in vernacular Chinese.
