The word u’mro-ata that is commonly referred to as the u’mra is a derivative from the root word ‘m-r where the apostrophe represents the ‘ayn consonant, a laryngeal without equivalent in any Western language.
The root word ‘amr arising from this root refers to the life of something. In the Reading, this word is used to refer to a continuous act or response carried out with a purpose. For example, if we want to give life to a barren land, we have to develop or cultivate it until we see the result. The Reading uses a’maru to denote this.
