The final irregular verb is 'willan - to want'. 'Willan' often comes paired with the infinitive form of another verb, just like in modern English. For example, I want to go, you want to see, he wants to drink. Examine the sentences 'Ic wille gangan to Rome - I want to go to Rome' and 'He wolde ðæt ða cnihtas cræft leornedon - He wanted the children to learn a craft'.
Though 'willan' looks like it should be translated to 'will', it is usually more correct to translate it as 'want' or 'intend' in the present tense. When in the past tense, it can be translated as either 'wanted' or 'would'. That's not to say it should never be translated as 'will', but consider 'intend' and 'want' first.
