“…Speaking of reading skills, many definitions refer specifically to "decoding" skills, which concern processing of single words, and can be said to be sufficient when single words are pronounced correctly. This has proven to be insufficient in that word-level skills are not exhausted with accurate singe-word decoding, but also encompass reading fluency, which refers to the speed, or efficiency, of processing (Fuchs et al, 2001;Wolf and Katzir-Cohen, 2001) and, crucially, involves word sequences rather than isolated words Altani et al, 2019).
