Usage Notes
When using Japanese words for technology, keep these cultural and linguistic points in mind:
- Katakana dominance: Most tech terms are written in katakana since they're borrowed from English. However, the pronunciation follows Japanese phonetic rules, so "computer" becomes konpyuutaa with elongated vowels.
- Abbreviations are common: Japanese speakers love shortening words. Pasokon (personal computer), sumaho (smartphone), and apuri (application) are more common in conversation than their full forms.
- Native vs. borrowed words: Some concepts have both native Japanese words and borrowed English terms. Gijutsu (技術) is the native word for technology, while tekunorojii (テクノロジー) is the borrowed English term. The native word often sounds more formal.
- Verbing with する: Many tech nouns become verbs by adding suru. For example: kensaku suru (to search), setsuzoku suru (to connect), daunroodo suru (to download).
- Politeness levels: When asking for tech help in formal situations, use -te kudasai forms: Setsumei shite kudasai (Please explain). In casual settings, -te alone works: Oshiete (Tell me).
