Usage:
{{te-verb-tense|<future verb stem>|<future continuous stem>|<present verb stem>}}
In most words, the future verb stem and present verb stem are the same (eg. with వేయు (vēyu), both verb stems would be వేస్- (vēs-)).
For the future continuous tense (going to do (-బోతున్నా- (-bōtunnā-)), the stem would be the the imperative/default form of the verb, but with the -ఉ (-u) changed to -అ (-a). Eg: వేయు (vēyu) in first person future continuous is వేయబోతున్నాను (vēyabōtunnānu).
