In this particular case, the present stem is reduplicated *di-dóh3-ti,
3pl. *dé-dh3-n.ti . This one is athematic, but there's also a thematic
variety (as represented by *si-sd-e-ti 'sit'), also correlated with root
aorists. Other possibilities include *-jé/ó- presents (like *gWm.-jé-ti
'walk') and athematic present stems with a nasal infix (like *k^l.neu-ti
'listen')
