Simple Background
Both words come from the noun instinct.
An instinct is a natural feeling or reaction that happens without careful thinking. People and animals often act on instinct when they react quickly to a situation.
Over time, English developed two adverbs from the word instinct:
| Base Word | New Word |
| Instinct | Instinctively |
| Instinct | Instinctually |
Both forms entered English and are still used today. However, one became much more popular in everyday language.
