In English, the words "that" and "so" are often used to increase the extent of an adjective (ex. "he is so tall" or "this food is so good"). In Chinese, 那么 (nàme) and 这么 (zhème) serve the same function.

Structure
All you have to do to use this grammar structure is put the 那么 or 这么 in front of the adjective.
