This paper deals with the expression of space in linguistic typology, more specifically with Path encoding. The term ''Path'' refers to the path followed by an entity with respect to another: for instance, in a scene where a cat runs and a table stands, Path will refer to the cat running past the table, below the table, down from the table, etc. The literature on how Path is encoded in different languages is abundant. This paper is not an exhaustive state-of-the-art review of the literature. It rather intends to guide the reader through major recent landmarks that would help one understand how typological generalizations about Path expression have been attained, what are such generalizations and how part of them still constitute an issue.Language and Linguistics Compass 6/4 (2012):
