Word recognition the integration of the different kinds of information occurs. The accuracy with which readers recognize words depends on the area of the retina that is stimulated. Reading in English selectively trains specific regions of the left hemiretina for processing this type of visual information, making this part of the visual field optimal for word recognition. As words drift from this optimal area, word recognition accuracy declines. Because of this training, effective neural organization develops in the corresponding left cerebral hemisphere. Eyes make brief, unnoticeable movements called saccades approximately three to four times per second. Saccades are separated by fixations, which
English words of Greek origin to recognize words of Greek origin, and give hints as to their pronunciation and inflection. Some romanizations are not completely standard.

The ligatures have largely fallen out of use worldwide; the digraphs are uncommon in American usage, but remain common in British usage. The spelling depends mostly on the variety of English, not on the particular word. Examples are: "encyclopaedia" / "encyclopædia" / "encyclopedia", "haemoglobin" / "hæmoglobin" / "hemoglobin", "oedema" /
