The present paper introduces a new variant of a scattered context grammar, called an LL leftmost k-linear scattered context grammar. It is an ordinary scattered context grammar without erasing rules, where (1) every scattered context rule is composed of k-linear rules, (2) if we take the first components of every rule, the resulting context-free grammar is an LL grammar, and (3) every rule is applied in a leftmost way. We study the generative power of this variant and its parsing properties, including time and space complexity. In the conclusion, several remarks regarding the achieved results are made.
