Letter I

Tinaband,

The rules are actually quite simple.

When in the nominative e.g. I, You, Him... it is always captial.

When the letter 'i' is contained within the spelling of a word and at the beginning of a sentence it is upper case. e.g. Islands often have a port or harbour to allow ships to dock.

When contained within a sentence and within the spelling of a word, it is lower case. e.g. The island I live on, has a harbour and a wharf.

Hope this helps.
