This sentence utilizes the causative-passive form of the verb, which is a key grammar point at the N3 level. ⚫︎ The causative form expresses that someone *makes* or *allows* someone else to do something. In this sentence, 洗わせます, is the causative form of the verb 洗います(to wash). ⚫︎ The base form of a verb is conjugated into the causative form using different rules based on which group the verb belongs to. In this case, 洗いますis a Group 1 verb and thus the conjugation rule is followed. ⚫︎ The causative-passive form combines the causative and passive forms to express that someone *is made to* or *is forced to* do something. Though this sentence doesn't explicitly have the nuances of forcing, the base form can be used for expressing being made to do something. ⚫︎ The general formula for the causative form of Group 1 verbs is: * Change the final -い sound to -あ sound, and add せる. * Example: 洗います becomes 洗わせます。 ⚫︎ In this sentence, the subject of the original action (washing) is the husband. The particle に marks the person being made to do the action. ⚫︎ In short, the entire sentence shows that the mother is making her husband wash the apples.

Japanese sentence structure, unlike English, is typically Subject-Object-Verb (SOV). ⚫︎ The sentence begins with the subject, in this case, 母(mother), marked by the topic particle は. ⚫︎ Next comes the indirect object, 夫に (to her husband). The particle に marks the indirect object, which is the person receiving the action. ⚫︎ The direct object is りんごを (apples), marked by the particle を. The particle を marks the direct object, which is what is being acted upon. ⚫︎ The verb, 洗わせます (makes wash), comes at the end of the sentence. This is the characteristic feature of the Japanese SOV structure.

Particles are crucial in Japanese grammar, as they indicate the grammatical function of words in a sentence. ⚫︎ は (topic particle): Introduces the topic of the sentence. In 母は, it indicates that the mother is the topic of the sentence. ⚫︎ に (indirect object particle/particle indicating direction): Indicates the indirect object of the verb, or to whom the action is being done. In this case, 夫に, the action is directed towards the husband. ⚫︎ を (direct object particle): Marks the direct object of the verb, which is what is acted upon. In りんごを, it marks the apples as the object of washing.

The verb in the sentence, 洗わせます, is in the ます (masu) form, which is a polite form of the verb. ⚫︎ The causative form of the verb is combined with the polite ます form to create a polite causative form. ⚫︎ The verb 洗います (to wash) is changed to its causative form, which is 洗わせる. ⚫︎ Then, the polite ending ます is added to make the sentence polite, resulting in 洗わせます. ⚫︎ This form is suitable for most conversations and makes the sentence sound more polite.

The auxiliary verb せる or させる is a crucial component of the causative form. ⚫︎ As explained earlier, せる is added to Group 1 verbs and させる is added to Group 2 verbs to form the causative form. ⚫︎ せる itself doesn't have a direct translation, but it indicates "making" or "allowing" someone to do something. ⚫︎ In this sentence, 洗わせる (causative of 洗う) is used to indicate that the mother is making her husband wash the apples. The auxiliary verb せる is responsible for that meaning.
