Mēda or Mān is one of the eldest non-big-nine symbols, so old it has it’s own hieroglyphic image. The hieroglyph looks like two surfaces held separate by two pillar gods and a figure standing in the middle.
Mēda covers the realm of “us-ness”. Ma, is me and mine, and us and ours. So ma can be used on the end of a sentence to denote a possessive:
This means, [tense marker]”here/now” + [object]”here/now” + [grammar] + [subject]”possessive”, which in colloquial English means “I’m online” or “I’m available” or “I’m here”. The ma on the end denotes a “me/I/mine” possessive.
At the beginning of a sentence, ma is usually used to denote an inclusive possessive, like “us”.
Mamān / amān [same word different dialect]
Means “All people” or “all of us”. But it’s only context and word order that differentiates whether the ma is me or us, so it can be confusing.
