The regular verbs of English use the -ed or -t inflection to form the past tense and past participle (eg ask → asked, deal → dealt). Irregular verbs do not. Many do not use any inflection for the past tense, but change the verb’s vowel. The vowel of the past participle is often different again, and often carries an -(e)n inflection.
break → broke/broken
[present tense → past tense/past participle]
Other irregular verbs to watch out for:
choose → chose/chosen speak → spoke/spoken steal → stole/stolen
drive → drove/driven rise → rose/risen write → wrote/written
swear → swore/sworn tear → tore/torn wear → wore/worn
blow → blew/blown grow → grew/grown know → knew/known
begin → began/begun sing → sang/sung swim → swam/swum
Some irregular verbs use irregular inflections to form the past tense and past participle (eg the past tense and past participle of bring are both brought, not bringed).

Future time
English lacks a future tense that is built into the verb, like -ed for the past tense. It more than makes up for it with several alternative verb phrases to express future time.
He will come this weekend. [modal verb phrase]
He is going to come this weekend. [modal paraphrase]
He is coming this weekend. [present tense, continuous aspect]
