Haava voi tulehtua nopeasti.

Questions & Answers about Haava voi tulehtua nopeasti.

This lesson covers -ntua verbs. Does tulehtua belong to the same group?
Yes! While it uses the slightly different -htua suffix, it is the exact same type of inchoative verb (expressing a change of state). It shows that the wound is becoming something on its own, rather than an outside force directly acting upon it.
What is the root word behind tulehtua?
It comes from the noun tuli (fire). With the inchoative suffix, it originally meant 'to catch fire'. In a medical context, it translates to 'to become inflamed' or 'to become infected'. This makes a lot of sense when you remember that an infected wound often feels hot to the touch!
How would I say that something actively causes the wound to become infected?
To express causing an action, you would use a causative verb ending, making it tulehduttaa (to infect / to cause inflammation). For example: Lika voi tulehduttaa haavan (Dirt can infect the wound).
Why is tulehtua in its dictionary form here instead of being conjugated?
It is paired with the modal verb voida (conjugated here as voi). Modal verbs always force the main action verb into its first infinitive (the dictionary form). Only the modal verb changes to match the subject, which is a great rule to remember for stringing verbs together.
