使用する際の注意点

• Although usage of "due to" as a disjunctive preposition is now common, some speakers will object and recommend because of, on account of, as a result of or owing to instead, reserving due for use as an adjective only. Reliable sources (such as Oxford, M-W, AHDictionary, etc.) acknowledge this debate, then conclude that more recently this usage of "due to" is widely, although perhaps not entirely, acceptable. Compare also the disjunctive use of based on. [1]
