Chpt 2 *stratum = layereditor's notes: Strata, the plural form of this word is used much more commonly than the singular form. Many Latin words that end in "um" are made plural by changing the "um" to "a"--such as stratum to strata, bacterium to bacteria, and millennium to millennia. In modern writing, changing the "um" to "ums" is also accepted for many Latin words ending in um, but not for any of those listed above.
