"In formal language theory, the left corner of a production rule in a context-free grammar is the left-most symbol on the right side of the rule. For example, in the rule A\u2192X\u03B1, X is the left corner. The left corner table associates to a symbol all possible left corners for that symbol, and the left corners of those symbols, etc. Given the grammar S \u2192 VPS \u2192 NP VPVP \u2192 V NPNP \u2192 DET N the left corner table is as follows. Left corners are used to add bottom-up filtering to a top-down parser, or top-down filtering to a bottom-up parser."@en . . . . . .
