Here’s an edited discussion of “spirit” from two reputable dictionaries, discussing the Biblical meaning of the word, for those that are interested. From this one can see how Biblical and clergy use would have influenced the modern use of the word. As already mentioned, it has more than one meaning.

PNEUMA (according to BDAG).
1. air in movement, blowing, breathing (even the glowing exhalations of a volcanic crater: Diod. S. 5, 7, 3).
a. wind
b. the breathing out of air, blowing, breath
2. that which animates or gives life to the body, breath, (life-)spirit
3. a part of human personality, spirit
4. an independent noncorporeal being, in contrast to a being that can be perceived by the physical senses, spirit (ELangton, Good and Evil Spirits ’42).
a. God personally:
b. good, or at least not expressly evil spirits or spirit-beings
c. evil spirits
5. God’s being as controlling influence, with focus on association with humans, Spirit, spirit as that which differentiates God fr. everything that is not God, as the divine power that produces all divine existence, as the divine element in which all divine life is carried on, as the bearer of every application of the divine will. All those who belong to God possess or receive this spirit and hence have a share in God’s life. This spirit also serves to distinguish Christians fr. all unbelievers (cp. PGM 4, 1121ff, where the spirit is greeted as one who enters devotees and, in accordance w. God’s will, separates them fr. themselves, i.e. fr. the purely human part of their nature); for this latter aspect s. esp. 6 below.
a. the Spirit of God, of the Lord (=God) etc.
b. the Spirit of Christ, of the Lord (=Christ) etc.
c. Because of its heavenly origin and nature this Spirit is called (the) Holy Spirit (cp. PGM 4, 510 ἵνα πνεύσῃ ἐν ἐμοὶ τὸ ἱερὸν πνεῦμα.—Neither Philo nor Josephus called the Spirit πν. ἅγιον; the former used θεῖον or θεοῦ πν., the latter πν. θεῖον: Ant. 4, 118; 8, 408; 10, 239; but ἅγιον πνεῦμα Orig. C. Cels 1, 40, 16).
d. abs.
e. The Spirit is more closely defined by a gen. of thing: τὸ πν. τῆς ἀληθείας (TestJud 20:5) J 14:17; 15:26; 16:13 (in these three places the Spirit of Truth is the Paraclete promised by Jesus upon his departure).
f. Of Christ ‘it is written’ in Scripture: (ἐγένετο) ὁ ἔσχατος Ἀδὰμ εἰς πνεῦμα ζῳοποιοῦν 1 Cor 15:45 . The scripture pass. upon which the first part of this verse is based is Gen 2:7 , where Wsd 15:11 also substitutes the words πνεῦμα ζωτικόν for πνοὴν ζωῆς (cp. Just., D. 6, 2). On the other hand, s. Philo, Leg. All. 1, 42 and s. the lit. s.v. Ἀδάμ ad loc.
g. The (divine) Pneuma stands in contrast to everything that characterizes this age or the finite world gener.: οὐ τὸ πν. τοῦ κόσμου ἀλλὰ τὸ πν. τὸ ἐκ τοῦ θεοῦ 1 Cor 2:12 ; cp. Eph 2:2 and 1 Ti 4:1ab .
α. in contrast to σάρξ, which is more closely connected w. sin than any other earthly material (Just., D. 135, 6): J 3:6; Ro 8:4-6 , 9a , 13 ; Gal 3:3 ; 5:17ab ; 6:8 . Cp. B 10:9. πᾶσα ἐπιθυμία κατὰ τοῦ πνεύματος στρατεύεται Pol 5:3.
β. in contrast to σῶμα (=σάρξ) Ro 8:10 and to σάρξ (=σῶμα, as many hold) J 6:63a (for τὸ πν. ἐστιν τὸ ζῳοποιοῦν cp. Philo, Op. Mund. 30; Herm. Wr. in Cyrill., C. Jul. I 556c=542, 24 Sc. the pneuma τὰ πάντα ζῳοποιεῖ καὶ τρέφει. S. also f above). Cp. Ro 8:11b .
γ. in contrast to γράμμα, which is the characteristic quality of God’s older declaration of the divine will in the law: Ro 2:29 ; 7:6 ; 2 Cor 3:6ab , 8 (cp. vs. 7).
δ. in contrast to the wisdom of humans 1 Cor 2:13 .
6. the Spirit of God as exhibited in the character or activity of God’s people or selected agents, Spirit, spirit (s. HPreisker, Geist u. Leben ’33).
7. an activating spirit that is not fr. God, spirit: πν. ἔτερον a different (kind of) spirit 2 Cor 11:4 . Cp. 2 Th 2:2 ; 1J 4:1-3 . Because there are persons activated by such spirits, it is necessary to test the var. kinds of spirits (the same problem Artem. 3, 20 περὶ διαφορᾶς μάντεων, οἷς δεῖ προσέχειν καὶ οἷς μή) 1 Cor 12:10 ; 1J 4:1b . ὁ διάβολος πληροῖ αὐτὸν αὐτοῦ πν. Hm 11:3. Also οὐκ οἴδατε ποίου πνεύματός ἐστε Lk 9:55 v .l. distinguishes betw. the spirit shown by Jesus’ disciples, and another kind of spirit.—Even more rarely a spirit divinely given that is not God’s own; so (in a quot. fr. Is 29:10 ) a πνεῦμα κατανύξεως Ro 11:8 .
8. an independent transcendent personality, the Spirit, Syn. II 218-50. New Docs 4, 38f. DELG s.v. πνέω. M-M. Dict. de la Bible XI 126-398. EDNT. TW. Sv.
Personal conclusion: From the above one can conclude that “spirit” refers to: 1) the energy involved, keeping the organism alive (where breathing plays an important part). The Bible refers to a living soul and a dead soul, the latter lacking “spirit.” 2) It can also refer to motivational energy of a person, whether internal or external, whether good or bad. 3) It can refer to an inanimate force, e.g., breeze, wind. 3) It can also refer to independent creatures, e.g., God, angels and demons.
