What is the difference between 跟着 and 跟? All dictionaries say that both can mean the verb "to follow".
If I want to use the 着 as a "particle indicating the continuation of an action or a state", should I use it once (跟着) or twice (跟着着)?
Other than serving as a particle indicating the continuation of an action or a state, 着 also serves an important function.
Both 跟 and 跟着 are verbs that mean "follow", however, 跟 also has the additional meaning of "and, with, to go with", which will cause ambiguity in a sentence. For example,
The expression "跟着着" is grammatically incorrect because the second "着" serves no function (which has been adequately taken care of by the particle immediately after the verb 跟).
