כתבינו לחיים. The tav has a (seemingly) short vowel to close the forst vowel, which sefardim pronounce as the short "kot". There is no meteg before the sh'va of the tav. Why is the bet written without a dagesh kal?
Note: This is unrelated to the discussion on how to pronounce a vet (some sefardim say "b" even without a dagesh). Even so, here it appears without a dagesh.
