The article examines the need for a terminological delimitation related to the concepts of „political coalition”, „political alliance”, „coalition government” and „parliamentary majority”. These terminological clarifi cations are needed to better understand the political processes and the governance act that take place in a democratic society. Particular attention is paid to the analysis of political constructions that was formed after the parliamentary elections of February 24, 2019, having as a background the political reason and the substantial procedural consensus. It is noted that the three political arrangements (the governing coalition between the Socialist Party and the political bloc „ACUM Platform DA and PAS”, the governing coalition between the Socialist Party and the Democratic Party, as well as the majority alliance of the Socialist Party – Șor Party – Parliamentary Platform „Pentru Moldova”), they all faced certain problems in their constitution, functionality and sustainability. In addition to all of these, the Socialist Party has established itself in all these political constructions as the dominant party of power. It is concluded that all the governing coalitions of the Republic of Moldova were extremely unstable and could not fully achieve the planned objectives for several reasons, the main being the multiaspectual and profound polarization of society. In addition, the division of political formations and their struggle on geopolitical criteria, the division of the national political elite in terms of the vector of strategic development of the country, lack of culture of dialogue and reasonable political compromise, the prevalence of petty group interests, corporate, against the general interests of society and so on they cannot determine lasting governing coalitions.
