דֶּתֶא (deteʾ) is
an Aramaic noun
meaning grass. It appears
2 times
in 1 book of the Hebrew Bible
(Strong's H1883).
Same Hebrew root (TWOT 2684)
Root family 2684: דֶּתֶאdeteʾ — grass. Used similarly to the Hebrew dešeʾ to which it is doubtless related. Words with a שִׁן (šin) in Hebrew characteristically shift to a תַּו (taw) in Aramaic if the Protosemitic sound had been “th” (Arabic “tha”)
