Verbs in the present tense usually end with the following:

-e, -st, -þ, -aþ

helpan - to help
iċ helpe | I help/am helping
þú hilpst | you help/are helping
hé, heó, hit hilpþ | he, she, it helps/is helping
wé, ġé, hié helpaþ | we, you, they help/are helping

lufian - to love
iċ lufie | I love/am loving
þú lufast | you love/are loving

wé, ġé, hié lufiaþ | we, you, they love/are loving

lǽran - to teach
iċ lǽre | I teach/am teaching
þú lǽrest | you teach/are teaching
hé, heó, hit lǽreþ | he, she, it teaches/is teaching
wé, ġé, hié lǽraþ | we, you, they teach/are teaching

and so forth.

Sometimes contractions happen

ċeósan - to choose
iċ ċeóse
þú ċiést (from ċiés’st, from ċiésest)
hé, heó, hit ċiést (from ċiés’t, from ċiés’þ, from ċiéseþ)
wé, ġé, hié ċeósaþ

Sometimes nouns look similar to verbs

cossas - kisses (noun, plural, nominative), from coss - a kiss
cossaþ - (third person (he/she/it) present verb), from cossian - to kiss

This is because some verbs are made from nouns.

lufu (love, noun) + -ian = lufian (to love)
coss (kiss, noun) + -ian = cossian (to kiss)

EDIT

Though cossian was later replaced by cyssan, which in turn became kissen in Middle English and then kiss in Modern English

cyssan - to kiss
iċ cysse
þú cyst (from cyss’st, from cyssest)
hé, heó, hit cyst (from cyss’þ, from cysseþ)
wé, ġé, hié cyssaþ
