A systematic name is a name given in a systematic way to one unique group, organism, object or chemical substance, out of a specific population or collection. Systematic names are usually part of a nomenclature.
A semisystematic name or semitrivial name is a name that has at least one systematic part and at least one trivial part.
Creating systematic names can be as simple as assigning a prefix or a number to each object (in which case they are a type of numbering scheme), or as complex as encoding the complete structure of the object in the name. Many systems combine some information about the named object with an extra sequence number to make it into a unique identifier.
Systematic names often co-exist with earlier common names assigned before the creation of any systematic naming system. For example, many common chemicals are still referred to by their common or trivial names, even by chemists.
In chemistry, a systematic name describes the chemical structure of a substance, thus giving some information about its chemical properties.
Nicholas:
She never really had a chance
On that fateful moonlit night
Sacrificed without a fight
A victim of her circumstance
Now that Ive become aware
And Ive exposed this tragedy
A sadness grows inside of me
It all seems so unfair
Im learning all about my life
By looking through her eyes
Just beyond the churchyard gates
Where the grass is overgrown
I saw the writing on her stone
I felt like I would suffocate
Inloving memory of our child
So innocent, eyes open wide
I felt so empty as I cried
Like part of me had died
Im learning all about my life
By looking through her eyes
And as her image
Wandered through my head
I wept just like a baby
As I lay awake in bed
And I know what its like
To lose someone you love
And this felt just the same
She wasnt given any choice
Desperation stole her voice
Ive been given so much more in life
Ive got a son, Ive got a wife
I had to suffer one last time
To grieve for her and say goodbye
Relive the anguish of my past
To find out who I was at last
The door has opened wide
Im turning with the tide
