Pertain comes to English via Anglo-French from the Latin verb pertinēre, meaning "to reach to" or "to belong." Pertinēre, in turn, was formed by combining the prefix per- (meaning "through") and tenēre ("to hold"). Tenēre is a popular root in English words and often manifests with the -tain spelling that can be seen in pertain. Other descendants include [abstain](https://www.merriam-webster.com/dictionary/abstain), [contain](https://www.merriam-webster.com/dictionary/contain), [detain](https://www.merriam-webster.com/dictionary/detain), [maintain](https://www.merriam-webster.com/dictionary/maintain), [obtain](https://www.merriam-webster.com/dictionary/obtain), [retain](https://www.merriam-webster.com/dictionary/retain), and [sustain](https://www.merriam-webster.com/dictionary/sustain), to name a few of the more common ones. Not every -tain word has tenēre in its ancestry, though. [Ascertain](https://www.merriam-webster.com/dictionary/ascertain), [attain](https://www.merriam-webster.com/dictionary/attain), and [certain](https://www.merriam-webster.com/dictionary/certain) are among the exceptions. And a few tenēre words don't follow the usual pattern: [tenacious](https://www.merriam-webster.com/dictionary/tenacious) and [tenure](https://www.merriam-webster.com/dictionary/tenure) are two.
