We had seen independent use of “To Want”. We can use “want” along with other verbs to indicate the desire for some activity.
e.g.
I want to watch this movie.
She wanted to eat a burger.
She needs to visit the doctor.

We have seen that in Marathi we have the same sentence formation for “To Need” and “To Want”. So below I have mentioned only about “To Want”. But it is exactly applicable for sentences with “To Need”.

In Marathi sentence formation is:

Form of subject with preposition "To" object Main verb + form of आयचा (AyachA)form of “असणे”(asaNe) as per object and tense
मलाआंबाखायचाहोता

The form of आयचा (AyachA) is created based on Gender and multiplicity of the object; similar to what we have seen in Adjectives.
i.e. it follows आ-ई-ए-ए-या-ई (A-I-e-e-yA-I) rule
I will summarize it as follows:

 Singular
Plural
Masculineआयचा ( AyachA )आयचे (Ayache)
Feminineआयची (AyachI)आयच्या (AyachyA)
Neuterआयचे (Ayache)आयची (AyachI)

Examples:

1) Masculine
e.g. Mango -> आंबा (AMbA)

Singular
I want to eat mango:- मला आंबा खायचा आहे (malA AMbA khAyachA Ahe)

Plural
I want to eat mangoes:- मला आंबे खायचे आहेत (malA AMbe khAyache Ahet)

2) Feminine

e.g.
Bag -> पेटी (peTI) ; open -> उघड (ughaD)

Singular
He wanted to open bag:- त्याला पेटी उघडायची होती (tyAlA peTI ughaDaayachI hotI)

Plural
He wanted to open bags:- त्याला पेट्या उघडायच्या होत्या (tyAlA peTyA ughaDaayachyA hotyA)

3) Neuter
e.g.

Song -> गाणे (gANe)
Singular
She will want to sing song:- तीला गाणे गायचे असेल (tIlA gANe gAyache asel)

Plural
She will want to sing songs:- तीला गाणी गायची असतील ( tIlA gANI gAyachI asatIl)

For अकर्मक verb ( i.e. the verb that does not require noun) form will always be be आयचे (Ayache)
e.g.
I wanted to go -> मला जायचे होते (malA jAyache hote )
I will want to run -> मला धावायचे असेल ( malA dhAvAyache asel )

Negative sentences

In English we say;
She does not want to eat.
He will not want to do this.

In Marathi Negative sentence formation is similar to the positive sentence seen above, only we will use the negative structure of”To Be” as per object and tense.

We have seen these forms at the very beginning of the course

Form of subject with preposition "To" object
Main verb + form of आयचा (AyachA)
Negative form of असणे”(asaNe) as per object and tense
मला (malA)आंबा (AMbA)
खायचा (khAyachA)नव्हता (navhatA)

e.g.
1) Masculine
e.g. Mango -> आंबा (AMbA)

Singular
I do not want to eat mango:- मला आंबा खायचा नाही आहे ( malA AMbA khAyachA nAhI Ahe
Plural
I do not want to eat mangoes:- मला आंबे खायचे नाही आहेत (malA AMbe khAyache nAhI Ahet)

2) Feminine
e.g. Bag -> पेटी (peTI) ; open -> उघड (ughaD)

Singular
He did not want to open bag:- त्याला पेटी उघडायची नव्ह्ती (tyAlA peTI ughaDaayachI navhtI)
Plural
He did not want to open bags:- त्याला पेट्या उघडायच्या नव्ह्त्या (tyAlA peTyA ughaDaayachyA navhtyA )

3) Neuter
e.g. Song -> गाणे (gANe)

Singular
She will not want to sing song:- तीला गाणे गायचे नसेल(tIlA gANe gAyache nasel)
She will not want to sing songs:- तीला गाणी गायची नसतील( tIlA gANI gAyachI nasatIl )

A sincere learner of this blog Mr. Chris has rightly pointed out in his comment on this topic that in all the above sentences the object is a non-living thing like mango, box, song, etc. ?
How should we construct the sentences when an object is a person or living thing?
I provided the answer in the comment. And I think this description is worth integrating with this lesson itself. So here is the answer :-

I will categorize it in in three different cases
1) You are talking about the third person(only for proper nouns and not pronouns). Then verb will be formed as per the gender of that person; as discussed in the above lesson.
e.g.
Kaushik wants to see Peter -> कौशिकला पीटर बघायचा आहे.(kaushikalA pITar baghAyachA Ahe.)
Kaushik wants to see Mery -> कौशिकला मेरी बघायची आहे.(kaushikalA merI baghAyachI Ahe)

2) Way 1 is grammatically correct but not a natural way. When talking about “persons”; we use “Preposition To” i.e. ला(lA) with the proper noun/ pronoun form. And the verb is always formed with neuter-singular gender.

Kaushik wants to see Peter -> कौशिकला पीटरला बघायचे आहे.(kaushikalA pITar baghAyache Ahe.)
Kaushik wants to see Mery -> कौशिकला मेरीला बघायचे आहे.(kaushikalA merI baghAyache Ahe)
Kaushik wants to see him -> कौशिकला त्याला बघायचे आहे. (kaushikalA tyAlA baghAyache Ahe.)
Kaushik wants to see them -> कौशिकला त्यांना बघायचे आहे. (kaushikalA tyAMnA baghAyache Ahe.)

So even for both genders & plurals, we used बघायचे(baghAyache) which is neuter-singular form.

3) For the first and second person; it is always as in case 2
Kaushik wants to see you -> कौशिकला तुला बघायचे आहे. (kaushikalA tulA baghAyache Ahe.)
Kaushik wants to see me-> कौशिकला मला बघायचे आहे. (kaushikalA malA baghAyache Ahe.)

Other funny examples:
I won’t eat you -> मला तुला खायचे आहे(malA tulA khAyache Ahe)
He did not want to open her -> त्याला तीला उघडायचे नव्हते (tyAlA tIlA ughaDaayache navhate )
