Questions & Answers about Allt tyder på att han har rätt.
What is the difference between tyder and tyder på?
By itself, the verb tyder usually means to "interpret" or "decipher" (like interpreting a dream or reading messy handwriting). However, when you add the preposition på, the phrasal verb tyder på changes to mean to "indicate," "suggest," or "point to."
Why are the preposition på and the conjunction att right next to each other?
The phrase tyder på needs a target to point at. Because the target here is a full clause with its own subject and verb (han har rätt), Swedish uses att to link them. While English often uses an -ing form ("points to him being right"), Swedish uses the preposition followed immediately by an att-clause. You cannot drop att here.
Why is allt used as the subject here instead of alla?
When used on its own as a standalone pronoun, the neuter singular form allt translates to "everything." If you used the plural form alla, it would mean "everyone" or "all people," which would change the sentence to mean "Everyone indicates that he is right."
Is it possible to say han är rätt instead of han har rätt?
