सोच

This means 'This is my thought.' The word order in Hindi is generally Subject-Object-Verb, and 'यह' (this) comes first.

This means 'What is your thought?' 'तुम्हारी' (your) modifies 'सोच' (thought), and 'क्या' (what) comes before 'है' (is).

This means 'My thinking is good.' 'मेरी' (my) modifies 'सोच' (thinking), and 'अच्छी' (good) describes 'सोच'.

This sentence translates to 'His/Her thinking always remains positive.' The word order for a declarative sentence in Hindi generally follows Subject-Object-Verb, and adjectives precede the nouns they modify. 'उसकी सोच' (his/her thinking) is the subject, 'हमेशा' (always) is an adverb, 'सकारात्मक' (positive) is an adjective modifying the implied state, and 'रहती है' (remains) is the verb.

This translates to 'Has there been any change in your thinking?' In an interrogative sentence (question) in Hindi, 'क्या' (what/if) often comes at the beginning. 'आपकी सोच में' (in your thinking) is a prepositional phrase, 'कोई बदलाव' (any change) is the object, and 'आया है' (has come/occurred) is the verb.

This sentence means 'This is the result of his/her deep thinking.' 'यह' (this) is the subject. 'उसकी गहरी सोच का' (of his/her deep thinking) acts as a possessive modifier for 'परिणाम' (result). 'परिणाम है' (is the result) is the predicate.
