How do you write english in katakana?

often its a simplified version, maybe to be easier to write or also just easier to pronounce. they also commonly use abbreviations, for example - *jeans is rarely seen as 'jeenzu' but almost always as 'G-pan / jii-pan' *rajikase = radio cassette recorder (raji = radio, kase = cassette) *Yshatsu = white shirt *famicon = family computer (ie playstation/gaming console) *pasokon = personal computer (PC) *baaten = bartender something i have learned after living in Japan for 9 months, is not to ask WHY. Its a question usually avoided and rarely answered satisfactorily. With borrowed words written in katakana there isn't really set rules, its not always about just copying english sounds as closely as possible. therre are many exceptions, and i often wonder why they write it one way when i think its more logicval another - classic example is using 'kya' instead of 'ka'. They say 'kyat' (cat) and 'kyarameru' (caramel) even though there is a perfectly good KA character in katakana. i have even seen the same word here spelled different ways, its rare but i have seen it.
