Sumar-tungl

Meaning of Old Norse word "sumar-tungl"

As defined by the Cleasby & Vigfusson Old Norse to English dictionary:

sumar-tungl

n. the ‘summer-moon,’ i. e. the moon at the time when summer begins. In popular belief one ought to notice when he first sees the summer-moon, and then mark the first word spoken by the first person he meets, for it is prophetic; this is called ‘svara einum í sumartunglið,’ ‘to address one at the summer-moon,’ see Ísl. Þjóðs.; in the Icel. Almanack for 1872 the 7th of April is marked as the ‘sumar-tungl.’
