**pre**fixes, short groups of letters that begin a word. Today we'll take a similar approach to a group of

**suffixes**- short groups of letters that end a word.

Not all of these are commonly used in mathematical calculations, but these

**suffixes**are common in the related fields of geometry, trigonometry, the other sciences, etc. If you want to be considered brainy, you need to know what they mean.

Please read through the list carefully - can you think of other suffixes that I missed?

Suffix | Meaning | Example |

-centenary | hundred years | bicentennial (200th) |

-gon | number of interior angles | polygon, hexagon, etc |

-gram | line overwritten or drawn on top | hexagram, 6-pointed star |

-graph | to draw, write or scratch | angiograph, paragraph |

-hedral, -on | number of faces or surfaces | polyhedral, hexahedron |

-ic | related to arts or sciences | arithmetic |

-lateral | ahead, before in line, first in order | equilateral |

-logy | to study; a body of knowledge | trilogy, ecology |

-ment | action, skill or process | assessment, alignment |

-metry | measuring | geometry, symmetry |

-nomial | a term in a math expression or formula | polynomial |

-oid | resembles, similar to | spheroid, cuboid, android |

-sect | to cut, divide or connect | intersect, bisect, trisect |

-scope | to examine or view | microscope, kaleidoscope |

-scribe | to write | transcribe, circumscribe |

-sphere | globe or ball | hemisphere, 3-sphere |

I think this will end my treatment of word prefixes and suffixes in the blog.

However, if you enjoyed it, go to this tremendous site. The creator says:

"

*Vocabulary is at the core of literacy and the more extensive our vocabulary is, the greater will be the understanding of what we read and hear.*"

Type a prefix or suffix into his search box, hit ENTER and then click on the result to get a list of words.

While searching around for prefixes and suffixes, I found this great math sentence:

*I have nothing more to say, because my mind grows*

**number**with each additional effort, and after eating a**number**of peppermint candies, my mouth has gotten**number**too.
