An archaic or variant spelling of 'eclipse,' the blocking of light from one celestial body by another.
From Old French 'eclipse,' derived from Greek 'ekleipsis' meaning 'abandonment' or 'failure to appear.' The 'e-' was sometimes dropped in older English texts.
Medieval scribes sometimes shortened words, and 'clipse' shows how spellings weren't standardized until recently—you might find this in old books where the sun 'clipses' the moon!
