In English, adverbs of manner (answering the question "how?") are often formed by adding "-ly" to adjectives, but flat adverbs (such as in "drive fast", "drive slow", and "drive friendly") have the same form as the corresponding adjective. Other languages often have similar methods for deriving adverbs from adjectives (French, for example, uses the suffix "-ment"), or else use the same form for both adjectives and adverbs, as in German and Dutch, where for example "schnell" or "snel", respectively, mean either "quick" or "quickly" depending on the context. Many other adverbs, however, are not related to adjectives in this way; they may be derived from other words or phrases, or may be single morphemes. Examples of such adverbs in English include "here, there, together, yesterday, aboard, very, almost", etc.
