Mighty Morph Don't Rhyme

A few-ish reasons:
1. The words are combination of different etymologies from different languages with different origins or ages

2. Because English is a natural language, not a constructed one like, say, Esperanto, which was constructed to be a international auxiliary language.

3. English has an alphabetic writing system. It has only 26 symbols to represent 44 sounds that, together, create millions of words. Unlike, let's say, Chinese which has an unlimited set of characters to display  meaning.

4. English is morphophonemic language so the way we write words is a code that represents both sound and meaning. Unlike, say, the Serbo-Croatian language where exact letter maps one-to-one with the sounds of the language.

Language is super fun! English is one of the languages with requires a some critical thinking but once you start to understand the roots, it can really open up a lot of fun discoveries.

The Sound of Scent

In "Scent," neither letter is silent.

Together, this combination of letters, create a softer sound than if one or the other was missing.

English is morphophonemic language - the letters represent a code for both sound and meaning - "scent," "sent" and "cent" are three separate words and actually are spoken (technically) in three different ways.

Double Your V

I got'ch!

In Classical Latin, the sound we make from the "w" (as in water) was represented by a letter that looked like "v." 

Through the years, the sound that the letter "v" changed to the modern sound - like vapor. 

To distinguish the sound of "w" from the "v" AND the up and coming letter-sound of "u," a double form of "u" was taken to represent the original Classical Latin "v" sound which was written as "uu" - which is two of those "u" symbols called  "double-u."
