Questions
Can I use 'tokoton' in formal business emails?
It's best to avoid it. 'Tokoton' has a conversational tone. In business contexts, it is better to use the more formal '徹底的に' (tetteiteki ni).
Does 'tokoton' have a positive or negative meaning?
It can be both, depending on the context. It has a positive nuance when talking about unwavering dedication, but can be negative when describing a stubborn, relentless argument.
What is the difference between 'tokoton' and 'sukkari'?
'Sukkari' means 'completely' regarding a state (e.g., completely forgetting, completely clearing up). 'Tokoton' means 'thoroughly' or 'to the end' regarding an active effort made by someone (e.g., investigating thoroughly).
