～ために, as hinted at in the introduction of the previous lesson, is not limited to expressing an objective. Another primary interpretation that may or may not coincide with an objective is expressing a cause. This lesson will help you understand exactly how to use and understand this "cause-marking" ～ために and how it contrasts and coincides with the "objective-marking" ～ために．
The cause-marking ～ために is used to express the cause of something in a reserved manner. It is equivalent to the English phrase “due to.” It can be seen after nouns, adjectival nouns, adjectives, and verbs. For conjugatable parts of speech, it can be seen after both the non-past and past tenses.
|Part of Speech||Non-Past Tense||Past Tense|
|Nouns||N + の + ため（に）||N + だった + ため（に）|
|Adjectival Nouns||Adj. N + な + ため（に）||Adj. N + だった + ため（に）|
|Adjectives||Adj. + ため（に）||Adj. + かった + ため（に）|
|Verbs||V + ため（に）||V + た + ため（に）|
The cause-marking ～ために is only used in declarative sentences and the questions made from said sentences. The basic sentence pattern with the cause-marking ために is “A + ために + B.” The A expresses cause if B is the result of A having occurred. Generally speaking, when the agent of A and B are the same, then ～ために expresses an objective, but when the agent of A and B differ, it expresses cause. This rule of thumb only works, though, with the non-past tense. When you see ～ため（に） after the past tense or the progressive form (～ている), or whenever both clauses lack a true active agent, then it is always the cause-marking interpretation.
Particle Note: The に in ～ために is frequently omitted, and when the statement is a positive one, it’s most natural to omit it. When に isn’t present, the statement is as neutral as can be. When に is present, the cause stands out more, but there is no emphasis as to whether the cause is good or bad.
Usage Note: This pattern is almost entirely used in the written language and/or in news(-like speech).

Grammar Note: ～ためか is equivalent to “perhaps due to.”
My father is working a part-time job and saving money because my older sister is marrying.
Sentence Note: It may also be the case that the father is saving the money so that his daughter may marry, but this would be something one must confirm whether this is true with the father.
My older sister is working a part-time job saving money in order to marry.
Sentence Note: Because the agent is the same in all clauses of the sentence, ために is interpreted here as “in order to.” The same can be said for Ex. 9.

～ます + ～ため（に）
There are also instances in which you will find the cause-marking ～ため（に） after polite endings such as ～ます, ～ました, and ～ません in attempt to be more formal. This is also almost entirely used in the written language. Some speakers frown on this practice, preferring the plain speech forms; however, it is nonetheless important to know that both ～ますため and ～ませんため are used a lot.
Particle Note: The particle に is seldom seen after ため in this situation.
Because I have yet to fully recover at this time, I plan on continuing my treatment through outpatient visits going forward.

Spelling Note: Although ため hasn’t been spelled as 為 elsewhere in this lesson, Ex. 23 particularly exemplifies the style of writing seen in business communications where other phrases that would otherwise not be written in 漢字 are to give off an overall formal feel.
Ambiguity Between Objective/Cause-Marking ～ため（に）
There are some situations in which the agent of A and B are the same. Sometimes this causes ambiguity as to whether ～ために expresses an objective or a cause.
①: When A is a noun, if the noun is one that describes an unrealized thing such as 成功 (success)・健康 (health)・幸福 (happiness), then it expresses an objective.
Get plenty of rest daily for your daily healthy as well.
②: If the noun expresses something that has happened/is happening such as 事故 (accident)・失敗 (failure)・あられ (hail), then it expresses cause.
The train has been delayed due to an accident.
We will postpone the game due to the rain.
We’ve now stopped to wait for a traffic light. We apologize for this inconvenience as you’re in a hurry.
Sentence Note: Although the use of “to” as the English translation may suggest that Ex. 27 demonstrates an objective, it is not the case that the vehicle stopped purposely to wait for a light. Although such a scenario is theoretically possible, it is also the case in English that “to” refers to cause. Changing the translation from “to” to “in order to,” for this reason, would be wrong.
③: For nouns—or even verbal expressions—in the middle that are neither positive nor negative things, only context can tell which interpretation is meant. Both interpretations can also be meant, which is also true for the English equivalent “for” and “to.”
I took a day off last week to get re-examined/for a re-examination.
I revved up and cleaned to welcome my mother.
