This is the 218th most frequent Icelandic word.
sagt
"Sagt" in Icelandic means "said" in English.
The word "sagt" is the past participle of the verb "að segja" (to say), used here in conjunction with the auxiliary verb "hef" to form the perfect tense.
Ég hef alltaf sagt sannleikann.
I have always told the truth.
In this sentence, "sagt" is again the past participle of "að segja," used with the auxiliary verb to indicate an action completed in the past.
Hann hefur sagt okkur skemmtilegar sögur.
He has told us entertaining stories.
Here, "sagt" is used impersonally to imply an unspecified speaker or source of information, reflecting hearsay.
