Pronunciation: [fˈɔːti θˈɜːd] (IPA) 
The spelling of "forty third" can be a bit confusing due to the unique pronunciation of the number 40. In IPA phonetic transcription, it is pronounced as /ˈfɔːti/ instead of /ˈfɔːti/ + /θ/ as one may expect. Therefore, the correct spelling of "forty third" is without the "u" typically seen in the word "fourth". The correct phonetic transcription would be /ˈfɔːti ˈθɜːd/.

The word forty comes from the Old English term feowertig, which means four tens. It is a combination of four (feower) and ten (tig).
The word third comes from the Old English term thridda, which derived from the Proto-Germanic word *thrijizdô. It continues back to the Proto-Indo-European root *tréyes, meaning three.
When these two words are joined, forty third represents the ordinal number that follows forty second and precedes forty fourth.
