Pronunciation: [stɹˌatɪɡɹˈafɪkə͡l] (IPA) 
The word "stratigraphical" is often used in geological contexts to describe the order and relative placement of layers of rock or sediment. Its spelling reflects its roots in the Greek language, with the "strat" component meaning "layers" and "graph" meaning "writing or drawing." The "ic" and "al" endings signify an adjective form. In IPA transcription, the word is pronounced /stɹætɪˈɡɹæfɪkl/.
Stratigraphical is an adjective that refers to something that is related to or deals with stratigraphy. Stratigraphy is a branch of geology that focuses on the study of rock layers or strata and their relationships, composition, and chronological order. It involves examining the sequential nature of layered deposits in order to decipher the geological history of an area.
When used in a geological context, stratigraphical often refers to the process of analyzing and interpreting the layers of rocks and sediments in various stratigraphic sequences. This can include studying the different types of organisms or fossils found in different layers, examining the changes in sedimentary structures, or understanding the formation and distribution of different rock types within a stratigraphic column.
In archaeological or paleontological contexts, stratigraphical is used to describe the analysis of layers or deposits to understand the relative chronology and cultural context of artifacts or fossils. By studying the order and relationship of these layers, researchers can establish temporal sequences and reconstruct important aspects of past environments, lifestyles, or evolutions.
Overall, stratigraphical is an adjective that pertains to the scientific examination and interpretation of rock layers or strata, aiming to reconstruct the formation, history, and relationships of geological, archaeological, or paleontological sites.
The arrangement or classification of any remains according to the stratum of the earth's crust to which they belong.

The word "stratigraphical" is derived from the combination of two components: "strati-" and "-graphical".
1. "Strati-" originates from the Greek word "stratos", meaning "layer" or "stratum". This element is commonly seen in terms related to layers or stratification, such as "stratigraphy" (the scientific study of rock layers) or "stratosphere" (the layer of the Earth's atmosphere above the troposphere).
2. "-Graphical" is derived from the Greek word "graphia", meaning "description" or "writing". This component is often associated with words involving the representation, study, or analysis of something. Examples include "cartography" (map-making), "biography" (written life story of an individual), or "geography" (study of the Earth's physical features).
