persevere

Use the verb persevere when you want to persist in anything and continue despite difficulties or obstacles.

The verb persevere comes from the Latin root persevereus which means "continue steadfastly, persist" and that word comes from two others, per- for "very" and severus for "strict." So, today, the connotation of the word is to persist in a methodical way despite obstacles or distractions. You can see the relationship between persevere and perseverate, which means "to persistently repeat something," and that word is a medical term used to describe stuttering.
